Cat Behavior Explained: 5 Reasons Cats Love Knocking Things Over

If your cat constantly sends pens, glasses, or decorations tumbling off shelves, you are not alone. 


While it may seem like your cat is being mischievous, there are several common reasons behind this behavior.


This guide about this common cat behavior explains why what may seem like mischievous behavior is often driven by several natural instincts and habits.

1. Curiosity and Exploration

Cats naturally explore their surroundings using their paws. While people rely on their hands to examine objects, cats often tap, bat, and push things to understand what they are.


A simple nudge can quickly become a full object launch from the edge of a table or countertop.


This type of behavior is especially common with new objects or items that have been moved to a different spot. Your cat may simply be investigating something unfamiliar.

2. Hunting Instincts Take Over

Even well-fed indoor cats still have strong hunting instincts. Small items that roll, wobble, swing, or slide can mimic the movement of prey and trigger your cat's natural urge to chase and capture.


Objects like keys, pens, bottle caps, hair ties, and small decorative items can become irresistible targets. What looks like random destruction may actually be your cat acting on instincts that are deeply built into their behavior.

3. Boredom Can Create New Entertainment

Cats need both physical activity and mental stimulation. When they do not have enough opportunities to play, climb, or explore, they often create their own forms of entertainment.


A shelf full of objects may become a game if your cat lacks enough enrichment throughout the day. Knocking items over provides movement, sound, and excitement, making it an easy way for your cat to stay occupied.


Regular play sessions and interactive toys can help redirect that energy into more appropriate activities.

4. Your Cat Wants Attention

Cats quickly learn which behaviors get a response. If knocking over a glass causes you to look over immediately, speak to them, or rush across the room, your cat may connect the behavior with getting attention.


To your cat, any response may feel rewarding if it leads to interaction.

Final Thoughts

Cats knock things over for many reasons, including curiosity, instincts, boredom, attention-seeking, and simple entertainment, so understanding the cause can help you redirect the behavior while keeping your favorite belongings safe.

The Big Social Media Debate: Should Cats be Indoor Pets or Outdoor

With the ongoing social media debate heating up over whether cats should be kept indoors or allowed outdoors, it’s time to look at the flip side of the argument. While there’s no question of a safety factor – for both the pet and the area wildlife – as well as the illness and parasite issue, there are some benefits to your pet roaming around outside - including exercise and natural mental stimulation.Here’s the problem for me. If you don’t live in an apartment where outdoor access is a non-starter, or you’ve adopted a kitten that hasn’t experienced the great outdoors and is content to be entertained through a window, it’s not easy to contain your feline to indoor living. I’ve tried.My two cats are rescues, so they had already been outdoors, and they definitely knew what they were missing. And that’s where I’ve been able to create a compromise that works for all involved. When I’m home, they’re allowed out onto the back deck and yard. No roaming free around the neighbourhood, and treats are always on the ready to entice them in. For one, it’s the distinctly sharp click of me snapping his IAMS double-pack that instantly draws him in from the very back of my yard. But allowing them out prior to a meal period helps ensure they come back in. Hint: appropriate fencing makes a difference. How to Keep an Outdoor Cat Safe?Have him vaccinated by your vet. Even if you don’t live in a ‘hood known for wildlife, your pet can pick up a wide range of serious illnesses, including the obvious rabies and the lesser-known feline herpes virus (FHV), feline calcivirus (FCV) and feline parvovirus (FPV), also known as distemper. They can even bring some of these viruses indoors on their fur and paws.

Ontario Dog Beats the Odds After Five Months in Sub-Zero Temps

As a dog parent, our worst nightmare is the sight of an open gate and an empty yard. Our minds instantly run to the worst-case scenario as we panic about our best friend's safety. For Collin, a resident of Stayner, a small town in Ontario, Canada, that nightmare became a reality on October 1, 2025, when his three-year-old Boxer-Rottweiler mix, Daisy, vanished. What followed was not just your typical tale of a lost dog. It was a five-month testament to a dog's resilience and to the incredible dedication of a community that refused to let her freeze. After sneaking out of the yard, Daisy was spotted by a local mechanic’s shop. While they tried to catch the loose dog, she was skittish and afraid, quickly taking off and disappearing from their sight. “Sightings poured in daily,” said Collin. “I lived vicariously through people posting sightings of her all over social media.”However, despite the many sightings, Daisy continued to elude rescuers and members of her local community. Days turned to weeks, and then months. Despite winter temperatures plummeting below -20F, the nervous pup managed to navigate harsh local storms and bitterly cold nights. Luckily, Daisy wasn’t fighting for survival alone. Local businesses like Hoffman’s Meat & European Deli and Rayne Nutrition stepped up, providing high-quality food to keep Daisy’s strength up, while Pet Valu Stayner provided essential supplies. Even the youngest members of the community pitched in. A young boy named Aidan helped shovel snow and sang to Daisy during feeding trips, focused on keeping the environment calm. Pawsitive Ground Search, a local organization dedicated to finding lost pets, brought their knowledge and expertise to the search. When a dog is lost for a long period, they often enter “ survival mode.” In this mental state, even the most loving pet can become anxious and skittish, failing to even recognize their own “people.” Collin experienced this firsthand when he came face-to-face with Daisy on the street, only for her to bolt away in fear. Sue, from Pawsitive Ground Search, introduced the importance of a “safe zone,” working tirelessly to keep Daisy’s frequent hiding spots and hangouts quiet and undisturbed. Changing a trap or making too much noise could cause a lost dog to vanish from sight for weeks. This highlights an important lesson for any dog parent: if a dog is in flight mode, chasing them is the worst thing you can do. The team and the many volunteers focused on consistency, delivering food twice daily to a barn where she had been seen seeking shelter. Finally, after 143 days in the wild, the breakthrough happened just after midnight on February 20. Using a live camera feed and a drop net, the team finally secured Daisy. Within seconds, the dog who had sparked hundreds of social media shares was headed home. Perhaps the most incredible part of the story is Daisy’s condition when she was finally trapped. After a vet checkup, Collin confirmed she is doing well and has settled back into her life of belly rubs and cuddles, as if she never left. Daisy’s story is a powerful reminder: never lose hope. If your pet ever goes missing, remember that the goal is to make them feel safe enough to stop running. Sometimes, providing a quiet place to eat is the most effective way to bring them back to the families who love them dearly. Join the PetGuide community.

Are All Nuts Good For Your Dog? Not Even Close!

As humans, we’re all about eating healthy, right? Okay, at least whenever we can. And nuts are a great source of healthy protein and good fats that support everything from a healthier sleep and better brain health to antioxidant delivery and anti-inflammatory benefits.But while all nuts are healthy, they do come with a few caveats. And you might be surprised to learn that it’s not just the obvious pancreatitis-triggering fat content. That’s why, while nuts can be a great treat for dogs, they need to be given in moderation and with a few considerations at play. Such as the type of nut and the format.For example, unsalted, unseasoned, and without added oils is the only way to go. For some nuts, such as almonds, a butter format is better than feeding your dog the whole nut due to the possible choking hazard.So, let’s talk about which nuts are safe for your pet and which should be avoided at all costs.If dogs can have a small number of peanuts or cashews, then they can also have the butter format, right? Yes, but only if it does not contain xylitol.Good Nuts for Your DogPeanuts: Shelled peanuts – raw or roasted – are a great treat for dogs. When we say treat, we’re talking three or four nuts a couple of times a day. Remember, no more than 10% of their daily caloric intake. Peanut protein is ideal for muscle development, the fat promotes healthy skin and a lustrous coat, with Vitamin E antioxidants and biotin supporting enhanced immune health. If you choose to go the peanut butter route, double-check your options to ensure they do not include the sweetener xylitol, which is highly toxic to pets. Go the organic route if you’re not sure.Cashews: Similar to peanuts, cashews deliver a bounty of antioxidants and Omega-3s as well as calcium, magnesium, phosphorus, and that all-important fibre every pooch needs. Whether served whole or in pieces, these nuts boost muscle tissue development, heart health, and promote skin and coat health. Choose to offer them in the whole nut format or a non-sweetened cashew butter that can be dobbed into his favourite Kong or puzzle toy.Almonds: Due to the size, shape, and firmness of this nut, you’ll want to be careful when doling them out. Dogs tend to gobble and can easily choke if they don’t chew properly. And if scarfed down whole, an almond can become lodged in his intestine, creating a blockage. That said, the nutritional benefits of this nut are numerous and worth exploring. Rich in Vitamin E (in the form of tocopherols and tocotrienols), antioxidants that promote heart, brain, and skin health. Check out an almond butter format that can add zinc, Omega-3 fatty acids, and magnesium to the mix.Bad Nuts for Your DogPistachios: While nutritionally rich, these nuts are extremely high in fat and calories as well as phosphorus, which can strain the kidneys and, potentially cause mold. Yes, mold. When pistachios are not properly dried or are stored in humid conditions, they can develop Aspergillus mould, which can produce carcinogenic toxins called aflatoxins.Macadamia nuts: Super high in fat, these nuts can easily trigger a serious bout of pancreatitis in dogs that will require medical attention. But there’s more, because a condition known as macadamia nut toxicity is also at play. While it’s uncertain what causes this level of toxicity, within a matter of hours of your pet consuming even a small portion (single nut), they can experience vomiting, tremors and weakness.Walnuts: The walnut tree and similar species, such as the pecan and hickory, produce a natural toxin called Juglone that permeates the tree roots, leaves, bark, and nuts. Guess what? When your dog consumes these nut meats, they can produce seizures and neurological disorders. Now, similar to pistachios, these nuts can be prone to mould and toxins that can prove fatal to your pet.

How To Stop Your Dog From Scratching At Your Carpets

Many dogs get into the habit of scratching at carpets. It’s frustrating, expensive, and often seems to start out of nowhere. However, the good news is that there’s usually a clear reason behind it—and once you figure out what’s driving the behavior, it becomes much easier to manage.Disclosure: PetGuide may receive a small affiliate commission from purchases made via links in this article but at no cost to you.

Common Signs of Mobility Loss in Dogs That Most Parents Miss

We all know that moment when it hits that our dogs are no longer the high-energy puppies they once were. It usually starts quietly. Maybe they hesitated for a second longer than usual, jumping on the bed this morning, or they took a little longer to find their footing after a nap. While these could simply be signs that your dog is slowing down naturally with age, they are also signs that their bodies may need a little extra support to keep up with their inner puppy. Seeing our best friends struggle with mobility can be heartbreaking, but aging doesn’t automatically mean they have to give up joy in their lives. It just means we need to change our approach. By catching issues like stiff joints or muscle loss early, we can make simple changes in our homes and lifestyles to keep them comfortable and confident. This post will help you do just that. Let’s look past the “old age” labels and talk about the real, actionable ways we can help our dogs stay mobile, happy, and right by our side for as long as possible. Disclosure: PetGuide may receive a small affiliate commission from purchases made via links in this article, but at no cost to you.The Most Common Mobility Challenges Faced by Senior Dogs Understanding the reason why your dog is moving differently is the first step toward helping them. While we often group everything under the umbrella of “getting gold,” there are a few distinct physical hurdles that most senior dogs will face during this stage of life. Recognizing which ones are affecting your dog allows you to tailor your care to best support their needs. Osteoarthritis and Joint Wear Osteoarthritis is perhaps the most common cause of limited movement in senior dogs. Over the years of hiking, playing fetch, and jumping, the protective cartilage that cushions their joints begins to thin. This leads to inflammation and bone-on-bone wear during movement, which causes them to feel stiff and uncomfortable. You might notice your dog hopping with their back legs together instead of stepping with each leg separately. This is commonly called “bunny hopping.” They may do this when trying to go up the stairs or when attempting to run across the yard after a squirrel. You may also notice your dog seems extra stiff on cold, damp mornings. This isn’t a loss of flexibility; it is a structural change in the joint that makes certain movements feel like a chore. The Hidden Impact of Muscle Wasting Many pet parents are surprised to see their dog’s hips looking sunken or their shoulder blades becoming more prominent during their golden years, even if their pup is still eating well. This is a condition known as sarcopenia, or age-related muscle wasting. As dogs age, their bodies become less efficient at maintaining muscle mass, especially in the hindquarters. This loss of muscle is more than just a change in their appearance. Your dog’s muscles act as the primary shock absorbers for their joints. When the muscle disappears, the joints have to take on the full impact of every step, which can contribute to the development of arthritis. The solution? Maintaining muscle through gentle, consistent, age-appropriate movement (more on that to follow). General Age-Related Decline Sometimes the change isn’t a limp or a specific weak spot, but a general loss of energy. This can be a combination of physical aches and pains and a possible mental gap. You might see your dog standing in a room and seeming to forget why they are there. This could range from a slight age-related fogginess to the development of canine cognitive dysfunction. If your dog feels unsteady on their feet, they may lose the confidence to explore as much as they once did, leading to a more sedentary life that further weakens their body. Less movement leads to more stiffness, which in turn leads to even less movement. Breaking this cycle is key to preserving your pup’s zest for life. When we look at these issues, it’s easy to see that mobility is a “use it or lose it” scenario. This means that by identifying mobility struggles, like joint pain, muscle loss, or a loss of confidence, you can begin making the adjustments needed to help your pup move forward more comfortably during this stage of life.  Creating a Safer Home EnvironmentOnce you understand the physical challenges your dog faces, the quickest way to improve their quality of life is to make small changes within your own four walls. Most modern homes are designed for human preferences, not for aging paws. At this stage of life, which is more important? Your home aesthetic or your best friend’s comfort? By performing a home audit, you can identify the daily obstacles that turn a simple walk to the water bowl into a stressful event and find solutions that work for both of you. Here are a few of the more common challenges many senior pups face: Traction and Slippery FloorsFor a senior dog with muscle wasting or stiff joints, a hardwood or tile floor can feel like walking on a sheet of ice. The constant little slips and missteps that happen while trying to stay upright can put an incredible strain on their hips and shoulders. If you notice your dog pacing the edges of a room or refusing to cross a certain hallway, they are likely afraid of falling. Instead of a full renovation, focus on creating safe trails throughout your home. Use non-slip rug runners or even affordable yoga mats to create a clear path between their favorite spots. For example, you can create a comfortable route from their bed to the food bowl and out the door. For areas where rugs aren’t an option, specialized toe grips or non-slip socks can give your pup that extra bit of confidence they need to move through their space without fear.
