Why is My Cat Not Grooming?

It’s a subtle shift that’s often easy to miss in the busy hustle and bustle of our days, but when your cat suddenly stops meticulously grooming themselves, it could be a red flag that something’s happening that requires your attention. For cats, grooming isn’t merely about maintaining a pristine appearance; it’s essential to their health, hygiene, and overall well-being. A sudden change in this self-care behavior could indicate anything from mild discomfort to a serious underlying medical concern.This post will share the reasons why your cat might be grooming less, what steps you can take to make them feel more comfortable, and, most importantly, when it’s time to seek immediate professional veterinary help. Why Grooming MattersFor cats, grooming serves many key functions, beginning with basic hygiene. Through their meticulous licking, cats remove loose fur, dirt, and any debris clinging to their coat, keeping themselves both clean and comfortable.Beyond just cleanliness, grooming helps to regulate their body temperature. Cats can use evaporative cooling to help dissipate heat and cool themselves down by spreading saliva across their fur. This is especially important during the warmer summer days.It’s also fundamental for skin health, as their tongues help to distribute natural oils. This keeps their skin moisturized while preventing dryness and irritation.Additionally, grooming can be a powerful social tool. When cats groom one another, it’s a way of communicating affection, trust, and social bonding. Psychologically, self-grooming has been shown to be calming, a routine behavior cats often use to reduce stress and anxiety.A healthy cat will typically groom themselves several times throughout the day, dedicating considerable time to cleaning every part of their bodies. Their barbed tongues act like tiny combs that untangle fur and remove debris. Their teeth also help with more stubborn knots. Finally, their paws are often moistened with saliva and used as a washcloth to help with harder-to-reach spots like the face and behind the ears. Causes for Decreased GroomingWhen your otherwise meticulously clean cat suddenly starts to neglect their grooming routine, it’s a red flag that you don’t want to ignore. This change can stem from many factors, ranging from environmental stressors to severe underlying medical conditions. Understanding these potential causes is the first step in getting the help and relief they need.Medical reasonsOften, a change in grooming habits is a direct symptom of feelings of pain or discomfort, making it difficult to physically move in the ways necessary to groom themselves. If a cat is hurting, the last thing they’ll want to do is bend, stretch, or twist into the various necessary positions. This pain can manifest in many ways: Arthritis or joint pain, especially common in older cats, can make movement painful.Dental problems like gum disease, tooth resorption, or abscesses can cause severe pain in the mouth or jaw, making licking unbearable.Spinal issues or injuries might restrict flexibility and cause discomfort when trying to reach certain areas.Abdominal pain or organ issues can make a cat feel unwell, leading to a disinterest in self-care and grooming.Wounds, abscesses, or skin infections are often painful to the touch, causing a cat to avoid grooming the affected area, or even grooming altogether due to generalized discomfort.Beyond localized pain, a cat’s grooming habits can suffer due to various underlying illnesses. Systemic diseases can leave your cat unwell, leading to lethargy or a lack of energy for typical daily activities (like grooming). Possible illnesses include: Kidney disease, which can cause nausea and weakness. Diabetes, leading to dehydration and lethargy. Hyperthyroidism, which can cause weight loss and muscle weakness despite an increased appetite.Various forms of cancer, which can cause widespread discomfort and poor health. Simple fevers or general feelings of unwell from a common infection can also impact your cat’s ability to groom. Obesity can also significantly impact your cat’s ability to move as needed for grooming. Overweight cats often struggle to reach certain areas of their body, particularly their back and hindquarters, making thorough grooming impossible. The extra weight can also contribute to existing joint pain, further limiting their mobility and desire to groom.If your cat is experiencing nausea or gastrointestinal problems, they will likely feel unwell enough to decrease their appetite and cause lethargy, leading to a disinterest in grooming.Finally, neurological issues can directly impact a cat’s ability to groom. Cognitive decline in older cats, similar to dementia in humans, can lead to a forgetfulness of routine behaviors, including grooming. If your cat has suffered a stroke or other neurological events, it may affect their motor skills and coordination, making the precise movements required for grooming difficult or impossible.Environmental and Behavioral FactorsWhile medical conditions are the most common cause, a cat’s emotional state and environment also play a crucial role in their grooming habits. Stress and anxiety can significantly impact normal behaviors, including grooming. Cats are creatures of habit, and disruptions to their routine can be incredibly upsetting. Common stressors include:Significant changes in routine, such as introducing a new pet, a new baby, or moving to a new home.Loud noises, home renovations, or ongoing conflict in the home can create a constant state of unease. Separation anxiety can also manifest in neglect of self-care. Prolonged stress can profoundly impact a cat’s overall well-being, leading them to neglect self-care activities like grooming.Similarly, depression or grief can cause a cat to withdraw and lose interest in their usual routines. This can occur after the loss of a companion animal or a human family member, or following other major life changes that deeply impact their emotional state.Aging naturally brings a decline in various bodily functions. Even without specific diseases, older cats often experience behavior changes. They may experience:A general decline in energy levels, making the effort of grooming less appealing.The onset of arthritis and other age-related discomforts make the physical movements required to groom difficult.Cognitive dysfunction, as mentioned earlier, can also contribute to forgetfulness or inability to perform grooming routines.Finally, while it’s less common for a prolonged failure to keep up with grooming, extreme heat or humidity can impact the thoroughness of a cat’s self-care. In very warm conditions, a cat may focus more on cooling behaviors, such as lying on cool surfaces or panting, rather than engaging in regular grooming sessions. However, this is unlikely to cause them to completely stop grooming unless accompanied by other symptoms.

Why is My Cat Suddenly Acting Aggressive?

Cats are well-known for their independent and aloof nature. It’s part of their mysterious and majestic presence. But what do you do when your once docile companion suddenly becomes angry or aggressive?Understanding why your cat may have shown such an abrupt behavior change is important. Why? This could be a sign of much bigger trouble that demands your attention. There are many explanations for this type of change in demeanor, including physical pain or illness. The best solution to create harmony once again in your home is to get to the bottom of it!In this article, we will look at the most common reasons for a cat to suddenly exhibit aggression and what you should do to help your furry best friend.What Does Aggression Look Like in Cats?If you are a first-time cat owner or have never encountered an aggressive cat, you may wonder what aggression looks like. Our feline friends aren’t always as outwardly friendly and affectionate as their canine counterparts, but aggression refers to behaviors that go a step further. Rather than being aloof or disinterested, an aggressive cat outwardly expresses upset, anger, and frustration toward a trigger.Cat parents who seek help with an aggressive cat often refer to their cat biting or swatting, causing physical harm out of nowhere. But there are often other signs of trouble that are overlooked or unnoticed.Early signs of aggression include:Thrashing or fast twitching tailDirect stareDilated pupilsEars flattened back against the headStiff or crouched postureRaised hacklesHissing, growling, or yowlingWhen these warning signs are ignored, a cat may feel they have no choice but to react further to protect themselves from the perceived threat or trigger. It is at this moment that a cat will swat or bite. Learning to recognize the early warning signs will help you prevent the situation from escalating to the point that someone is hurt.How Do You Tell if a Cat is Playing or Being Aggressive?Some cats, especially young kittens, may play in a way that is similar to or mimics the signs of aggression. This can make it harder to identify if your cat is truly upset or simply playing around. Luckily, there are a few minor differences that can help you differentiate between the two.When a cat is being playful, they usually have their claws retracted. This means they may swat at you during play, but they aren’t scratching or causing harm with that action. The same can be said when they pounce on you – landing on you with their paws, nails retracted. If your cat is biting at your hand during play, they often have a threshold they won’t cross. They may bite hard enough that you feel some discomfort, but they aren’t trying to break the skin.There is a grey area that shouldn’t be overlooked between play and aggression, where a cat either didn’t learn where that line exists or fails to acknowledge it. This is known as play aggression, which we will touch on later.

Why Is My Cat Avoiding the Litter Box?

Cats are known for their strong instinct for cleanliness, and most will use a litter box without issue. So, when your feline companion suddenly starts avoiding it, this can be a sign of an underlying problem. The reasons can range from medical conditions to environmental stressors, and identifying the cause is crucial for resolving the issue. Here are some of the most common reasons why your cat is avoiding the litter box.#1 Medical IssuesOne of the first things to consider is a medical condition. Cats experiencing pain or discomfort while urinating may associate the litter box with that discomfort and avoid it altogether. Common health issues that can lead to litter box avoidance include:Urinary Tract Infections (UTIs) – Can cause pain, frequent urination, and accidents outside the box.Feline Lower Urinary Tract Disease (FLUTD) – Often leads to straining, frequent attempts to urinate, and licking of the genital area.Bladder Stones or Kidney Disease – May cause increased urination or discomfort.Diabetes – Can result in excessive thirst and urination, sometimes overwhelming the litter box.If your cat is exhibiting signs of discomfort, straining, or unusual urination patterns, a vet visit is essential to rule out these conditions.#2 Hygiene and Litter Box MaintenanceCats are fastidious creatures, and a dirty litter box can be a major deterrent. If the box isn’t cleaned regularly, your cat may seek alternative places to relieve itself. To maintain a clean and inviting space:Scoop the litter box daily to remove waste.Perform a full clean weekly, replacing old litter with fresh, unscented litter.Use an appropriately sized litter box—cats generally prefer a box at least 1.5 times their body length.Place the box in a quiet, low-traffic area where your cat feels safe.

Why Has My Cat Suddenly Gone Off Their Food?

Cats are known for being picky eaters, so it’s not unusual for them to turn their noses up at a meal now and then. But if your feline friend suddenly stops eating altogether, it’s natural to feel a little concerned.Often, a loss of appetite is simply your cat’s way of saying something’s off — and in many cases, the cause is something minor and easily managed. Occasionally, it might point to something that needs attention from your vet.Let’s take a closer look at some common reasons your cat may have gone off their food, and the simple steps you can take to help them get back on track.

Why Has My Senior Dog Started Having Accidents Indoors?

Finding a surprise puddle on the floor from a dog who has been perfectly house-trained for years can be heartbreaking. Your first reaction might be confusion, or even a brief flash of frustration, but that is quickly replaced by a sense of worry. You know your dog isn’t doing this to be spiteful or lazy; they are trying to tell you that something is “off” in their world. As our dogs cross into their senior years, sudden indoor accidents are rarely a choice. They are almost always a sign that your best friend’s body or mind needs a little extra care and support. Navigating this new chapter can feel overwhelming. But understanding exactly why it’s happening is the first step toward restoring your dog’s comfort and protecting your home. Disclosure: PetGuide may receive a small affiliate commission from purchases made via links in this article, but at no cost to you.Physical CausesWhen a senior dog begins having accidents inside, the first step is always to look at the potential physical cues and what they may be trying to tell you. In many cases, your dog knows exactly where they are supposed to go, but a medical condition or physical limitation makes it impossible for them to stick to the routine. Here are the most common physical culprits behind a senior dog having potty accidents: Urinary Tract Infections (UTIs)An infection is one of the most common reasons a reliably trained dog is suddenly having accidents in the home. When harmful bacteria compromise the lining of the bladder and urethra, it causes painful inflammation and sudden, intense spasms. This creates an overwhelming need to urinate, and urinate immediately, leaving your dog with very little warning to make it to the door, let alone wait for you to let them out. Senior dogs, particularly females, dogs with weakened immune systems, or those with underlying conditions like diabetes, are all highly susceptible to these infections. In addition to the accidents, you may also notice blood in the urine or that your pup is frequently squatting, straining, or crying out when trying to go outdoors, with little or no urine released. Hormone-Responsive Urinary Incontinence This condition is completely involuntary, meaning your dog has absolutely no control over when or where it happens. As dogs age, declining hormone levels (specifically estrogen in spayed females and testosterone in neutered males) can weaken the urethral sphincter, the muscle that holds urine in the bladder. Because of this weakness, urine may leak out, typically when your dog is completely relaxed. You will often notice wet spots on their bedding or a trail of drops as they stand up from a nap, and the dog is usually just as surprised by the leak as you are. Osteoarthritis and Mobility IssuesSometimes the issue isn’t with the bladder at all but with the joints and spine. If a senior dog is dealing with stiff, painful joints or spinal issues, the physical act of getting up from a bed, navigating slippery floors, or managing stairs to go outside can become a grueling task. Because it hurts to move, your dog may wait until the very last second to signal that they need to go out, and by the time they build up the momentum, it is too late. Furthermore, weakness in the hind end can make it difficult or painful to maintain a steady squat or leg-lift posture long enough to empty their bladder or bowels completely outside, leading to accidents shortly after they come back indoors. Systemic Metabolic Diseases There are several age-related health conditions that can drastically change how your dog’s body processes fluids. Diseases like Diabetes Mellitus, Cushing’s Disease, and Chronic Kidney Disease all trigger a cycle of increased thirst and, with that, increased urination. Because these conditions force the body to drink massive amounts of water to flush out toxins or regulate glucose, the bladder fills up much faster. A dog who used to comfortably hold their bladder for six hours may suddenly need to relieve themselves every two hours, easily outpacing their normal schedule. Gastrointestinal and Fecal Incontinence While bladder issues are more common, sudden fecal accidents can also point to changes in your dog’s aging body. Spinal cord degeneration or nerve damage in the lower back can interrupt the signals between the brain and the rectum, meaning your dog may literally not feel that they need to go to the bathroom until the stool is already passing. Additionally, senior dogs can develop age-related food intolerances, inflammatory bowel conditions, or a loss of efficiency in their digestive system, leading to sudden bouts of bathroom urgency that are impossible for them to stop. Cognitive Causes When physical health conditions have been ruled out by your veterinarian, the focus shifts from the body to the brain. It can be jarring to realize that your dog hasn’t lost the physical capacity to hold their bladder, but rather the mental know-how to stick to their lifelong training. In aging pups, this is most frequently caused by a condition known as Canine Cognitive Dysfunction, or CCD. Understanding Canine Cognitive Dysfunction CCD is the veterinary equivalent of dementia or Alzheimer’s disease in people. As a dog’s brain ages, it can undergo changes, including the accumulation of cellular waste products like amyloid plaques and a decrease in overall blood flow. These changes gradually impact your dog’s memory, learning, and spatial awareness. For a senior dog, this directly affects their ability to stick to their everyday routines, including the house-training rules they have followed perfectly for years.  CCD and House-Training Accidents When CCD takes hold, a dog can literally forget where they are supposed to go to the bathroom. The mental boundary between “inside the house” and “outside in the yard” begins to blur. You might notice your dog standing by the back door, looking out into the yard as if they want to go, only to turn around, walk into the living room, and relieve themselves on the rug. They are not doing this out of defiance or laziness; their brain simply failed to connect the signal of a full bladder with the physical location of the yard. In other cases, they may lose the ability to signal their needs altogether, not knowing they need to go until it’s too late. They are as confused by their own sudden accidents as you are. Recognizing the SignsAccidents in the house are rarely the only sign that a dog is dealing with cognitive decline. Vets use a helpful acronym, DISHA, to help pet parents identify and track the signs of CCD. If your senior dog’s change in bathroom habits is accompanied by any of these other behavioral shifts, it is a strong indicator that the root cause rests in the brain:Disorientation: Staring blankly at walls, getting stuck behind doors or in corners, or failing to recognize familiar people and environmentsInteractions: Noticeable changes in how they socialize, such as becoming unusually clingy, anxious, or, conversely, distant and detached from their family.Sleep-Wake Cycles: Pacing, whining, or wandering aimlessly through the house at night while sleeping heavily throughout the day.House Soiling: The sudden loss of voluntary bladder or bowel control indoors, often happening right after coming inside from a walk.Activity Changes: A general decrease in participating in their favorite activities, or an increase in repetitive behaviors like wandering circles without a clear destination.Recognizing these changes early will allow you to approach the situation with the right mindset. Understanding that your dog is navigating a confusing mental fog makes it easier to respond with the patience, supportive home environment, and medical care they truly need to thrive.

STARS Air Ambulance Welcomes Orion as Their New Therapy Dog

For those of us who share our lives with pets, we know that their very presence can change the energy of a room. Whether it’s a quiet evening at home or a stressful afternoon, our animals help to ground and calm us. Recently, STARS Air Ambulance, an organization known for high-stakes, life-saving missions, decided to bring that same benefit to its frontline crews by welcoming a very special new team member, Orion. Orion is a professionally trained therapy dog provided by the Pacific Assisted Dog Society (PADS). Since joining the team in February 2025, he has become a fixture at the Winnipeg base, though his calming influence and energy extend across the STARS network. His primary role with the team is to support the pilots, paramedics, and flight nurses who work daily in environments and situations that involve extreme stress and trauma.  “What our plan is, to evaluate the first two years with a therapy dog and decide from there to expand the program and whether that will include additional dogs in each province or each of our six bases,” explained Grant Therrien, providing director for Manitoba STARS operations, STARS flight paramedic, and Orion’s handler. While we often use the terms interchangeably, Orion’s role is distinctly different from that of a service dog. A service dog is specifically trained to perform tasks for a single individual with a disability, such as guiding someone with visual impairment or alerting a person to an impending seizure so that they can prepare themselves accordingly. These dogs have specific legal public access rights because they are considered essential medical equipment. In contrast, a therapy dog like Orion is trained to provide emotional and psychological comfort to many people. These dogs must have an exceptionally calm temperament and enjoy being handled by people, especially strangers. Their “job” is presence. By simply sitting with a flight crew after a difficult mission, Orion helps lower cortisol levels and heart rates, helping them back to a calmer state of mind. Orion’s work is not limited to the staff. He has also become a key resource for former patients and their families. When survivors return to the base to meet the crews who saved them, the emotions they experience can be overwhelming. Orion often stands with these families, offering a quiet, reassuring presence that makes a sensitive conversation and difficult memories a little easier to navigate. The addition of Orion to the STARS team is a clear reminder of what pet parents have always known: the bond between humans and animals is a powerful tool for healing. In the world of emergency medicine, where every second counts, Orion reminds the team to take a breath. He proves that sometimes the most effective way to care for those who save lives is provide them with a loyal friend who is always ready to listen. Join the PetGuide community.
