Published: July 2nd, 2025

Creating a vibrant flower garden doesn’t mean compromising your cat’s safety. Many popular blooms are toxic to cats, but with a little planning, you can cultivate a beautiful, colorful space that’s also non-toxic and feline-friendly.

Whether your cat enjoys basking in the sun or nibbling on greenery, here’s how to design a gorgeous garden that both you and your pet can enjoy worry-free.

1. Choose cat-safe flowers first

Many common flowers can be dangerous for cats, so carefully selecting your plants is really important. Here’s a curated list of non-toxic flowers that are safe for cats and also stunning in any garden:

🌼 Cat-safe flowers

These flowers are listed as non-toxic to cats by the ASPCA:

Calendula (Pot Marigold) – Cheerful yellow-orange blooms that attract pollinators.
Snapdragons – Tall, spiky flowers in a rainbow of colors.
Zinnias – Hardy annuals with vibrant, daisy-like flowers.
Roses – While the thorns can be a hazard, the petals are non-toxic.
Sunflowers – Bold and bee-friendly, these are safe if nibbled.
Petunias – Classic garden favorites that are non-toxic to cats.
Gerbera Daisies – Bright and bold blooms that are perfectly safe.
Asters – Autumn bloomers that add soft color and are cat-safe.
Bachelor’s Buttons (Cornflowers) – Delicate blue flowers that are harmless to cats.

🌱 Note: "Marigolds" commonly sold in garden centers may refer to Tagetes (which are mildly toxic). Look for Calendula officinalis (pot marigold), which is non-toxic.

2. Avoid these toxic blooms

To keep your garden safe, steer clear of the following popular flowers that are toxic to cats (please note that this list isn’t exhaustive):

Lilies (especially Easter, Tiger, and Asiatic lilies – extremely toxic)
Daffodils
Tulips
Hyacinths
Iris
Foxglove
Peonies
Chrysanthemums

Even small amounts of these plants, particularly lilies, can cause severe illness or death in cats.

3. Designing a cat-safe flower garden

Once you’ve selected safe flowers, it’s time to design your garden.

🐾 Low flower beds and lounging spots

Keep some areas with low-growing, soft flowers like petunias or zinnias where cats can lounge or sunbathe nearby.

🌸 Height variation

Use a mix of heights, like snapdragons in the back, zinnias in the middle, and pansies in the front, to create visual interest and layered flower beds that are safe from root to petal.

🌿 Include cat-favorite plants

If you want to spoil your cat, intersperse flowering plants with cat-favorite greenery like:

Catnip (Nepeta cataria)
Catmint (Nepeta faassenii) – adds lavender-colored flowers and entices cats naturally
Lemongrass or Wheatgrass – safe for nibbling and aids digestion

4. Go organic

Even the safest flower garden can become hazardous if chemicals are involved. Avoid putting down:

Pesticides and herbicides
Chemical fertilizers
Cocoa mulch (toxic to cats like chocolate)

Instead, opt for:

Organic compost
Neem oil or insecticidal soap for pests
Straw or shredded bark mulch (unscented and natural)

Final thoughts

A flower garden doesn’t need to be off-limits to pets. With careful flower selection and mindful design, you can grow a space that bursts with color while being completely safe for your feline companions.

Whether you want a fragrant patch of calendula and daisies or a vibrant bed of petunias and snapdragons, a cat-safe flower garden is totally achievable—and it looks absolutely stunning.

Pretty Plants that Will Stop Cats from Pooping in Your Garden

Whether you own a cat or neighboring felines like to frequent your backyard, chances are you have come across half-buried cat poop in your flower beds. Cat lover or not, you probably weren’t thrilled to discover these unsightly deposits in your garden.Although cat poop won’t harm your garden, it also won’t add much to the overall appeal of it either, especially if the cats decide to dig their own toilets in the middle of your flower patch. In addition to preserving the aesthetics of your garden, there are several other reasons you may want to stop cats from pooping in your backyard. Keeping cats away will ensure the garden stays clean and safe for young children to play in. Plus, it will help protect wild birds that visit your garden, especially if you have a bird feeder or two.Besides being unsightly, cat poop in the garden can carry a parasite, called Toxoplasma gondii, which is particularly dangerous to pregnant women and unborn babies. For this reason, it’s super important that you wear gloves when you clean cat poop from your garden. As an added precaution against nasty infections, always use gloves when gardening.Are you sick and tired of cats using your garden as their personal toilet? There are several things you can do to preserve your outdoor oasis that don’t include the use of cruel booby-traps or startling devices.All you have to do is buy the right plant - one that cats hate but will look great in your garden. Although technically a weed, the curry plant is one of the best plants to deter cats from pooping in your garden. Scientifically known as Helichrysum italicum, the curry plant is a small, bushy evergreen shrub with linear-shaped silver-gray leaves. The leaves have a strong odor, reminiscent of curry, that acts as a potent cat deterrent. When a cat brushes against a curry plant, its leaves release a strong odor that attacks a cat’s sense of smell. Plus, the curry plant also has a coarse texture that cats hate. Many gardeners agree that curry plants act as excellent cat deterrents saying that cats stopped pooping in their gardens after they planted curry plants. Since the curry plant is essentially a weed, plant it sparingly so it won’t spread and take up too much space. If, for whatever reason, you don’t want to plant curry plants in your garden, plant lavender instead. A popular ornamental plant, lavender has pretty purple flowers and a delicate and sweet smell with herbal undertones. It’s that delicate smell that will help keep cats away from your garden!Cats have more than 200 million odor sensors in their noses and anything that emits a strong smell, like lavender, will be off-putting. Luckily, lavender is easy to grow and you can plant it in any part of your garden or containers. This gives you the freedom to plant lavender exactly where the cats like to poop to deter them. Many cats also dislike the smell of rosemary, rue, pennyroyal, citronella, oregano, geraniums, lemon thyme, and coffee. Any of these plants can act as a natural barrier and discourage cats from entering your garden and using it as a toilet. Although there are other ways to deter cats from pooping in your backyard, planting plants is an entirely natural and non-toxic option that isn’t harmful to the cats or you. It’s also cost-effective and aesthetically pleasing. Join the PetGuide community. Get the latest pet news and product recommendations by subscribing to our newsletter here.

Why Is My Fish Lying at the Bottom of the Tank?

Fish can have all sorts of quirky behaviors, but spotting your fish lying motionless at the bottom of the tank can be a cause for concern. While it might look alarming, this isn’t always a sign of illness. In fact, many fish naturally rest or explore near the substrate. That said, if this behavior is sudden, prolonged, or comes with other signs of distress, it’s worth taking a closer look.Normal or Not? Understanding the BehaviorFirst, it’s helpful to know what’s normal for your particular fish species. Bottom-dwelling species like catfish, loaches, and other scavengers often spend much of their time at the bottom. They’re built for it - searching for food, resting, or hiding among decorations. But if a fish that typically swims in the upper or middle areas suddenly starts lying low, that could signal a problem.Some red flags to watch for include:Clamped finsDiscolorationGasping at the surfaceLoss of appetiteLabored breathingErratic or unusual swimmingIf any of these symptoms accompany bottom-sitting, it's time to investigate.

Virtual Dog Therapy Opens New Doors for Mental Wellbeing

For those of us who share our homes and our lives with a dog, we already know the truth: just a few short minutes spent with our pet can melt away the day’s stress. It’s a special connection that defines the human-animal bond. Now, new scientific research is not only validating the power of this bond but also proving that the benefits it offers are so strong they can be shared through a screen. In a recent study conducted by UBC Okanagan (UBCO), researchers found that even a virtual session with a therapy dog can significantly reduce a person’s stress. It’s a discovery that has big implications for our mental health and well-being. The study, led by Dr. John-Tyler Binfet, Director of UBCO’s Building Academic Retention through K9s (B.A.R.K.) program, and Dr. Christine Tardif-Williams, builds on earlier work that examined the impact of dog-assisted mental health interventions. The goal was to find a way to make the benefits of spending time with a therapy dog more accessible to the public, especially after the increased isolation and demand for virtual medical appointments seen during the pandemic. The findings, published in Human-Animal Interactions, were really promising. Over 1000 participants (including both students and community members) watched a five-minute pre-recorded video featuring a therapy dog and a handler. The videos featured key aspects of the in-person therapy dog experience, including calm conversations and guided reflection. Each participant completed a short stress survey before and after the session. After comparing the surveys, researchers determined that participants experienced a noticeable drop in their stress levels simply by watching the short clip. “The results suggest that virtual therapy dog interventions can also benefit the broader public, particularly those who face barriers to accessing in-person mental health support, such as access to outside of normal operating hours or from a remote location,” explained Binfet. With the growing interest in telehealth services and similar alternatives in our lives, both for us and for pet care, the availability of virtual therapy dog appointments could be a game-changer for many who need it. It’s also a clear validation for those of us who have been saying that sharing our lives with our pets has a positive overall impact on our health and well-being. If a pre-recorded five-minute video of a dog can effectively lower stress, imagine the impact of spending your life with the warm, breathing, loving presence of a pet right next to you. When we interact positively with an animal, whether through petting, playing, or even just looking at them, it directly impacts our brain chemistry. The interaction triggers a release of oxytocin, known as the “love hormone,” which makes us feel happy and connected. At the same time, it lowers the production of the stress hormone cortisol. Combined, this shift leaves us feeling happier, less stressed, and more content. Ultimately, this research is a reminder that the best therapy is often sitting right beside you, waiting for a belly rub. The discoveries in this study highlight an excellent opportunity for greater accessibility for everyone to benefit from the healing power of therapy dogs, even when an in-person appointment isn’t possible.

Is Catnip Bad for Dogs?

Have you recently noticed your dog sniffing around your cat’s favorite toy? If so, you may find yourself wondering why your dog is drawn to something clearly designed for cats. After all, it’s called “cat” nip for a reason, right?This harmless-looking herb drives our cats into a frenzy of rolling, drooling, and playful craziness. But what happens if your dog ingests the leafy green? Does it cause the same “high”? Is it even safe? And, perhaps most importantly, could the herb that’s famous for making cats go wild actually offer any potential benefits for our pups? After all, we want to give our dogs the happiest lives possible, and that sometimes means exploring options outside of the usual dog-specific products.In this article, I’ll answer these questions and more.What Exactly is Catnip?You’ve likely seen catnip mentioned a million times when it comes to cats’ toys, but what exactly is it? To understand how it interacts with your dog, we first need to know exactly what it is. It’s much more than just a novelty for the kitties in our lives; it’s an herb with a long history, even in human tradition.Catnip, scientifically known as Nepeta cataria, is a perennial herb in the mint family. It’s native to parts of Europe, Asia, and the Middle East, but it now grows readily around the world. In fact, you can likely buy catnip seeds in your local garden center. Historically, long before it was known for entertaining housecats, humans used it in herbal teas for its calming and mild sedative properties. It was also sometimes used to improve digestion. The reason catnip attracts so much attention centers on one specific volatile oil: Nepetalactone. This oil is contained within the leaves, stems, and seed pods of the plant.In cats, it’s the nepetalactone that triggers the short-term neurological reaction that we see, aka the crazy burst of energy that they get when they get near it. However, as I’ll explain in the next section, the canine system processes the chemical very differently. It’s unlikely to start zooming around the room after a sniff.Is Catnip Safe for Dogs?Returning to the original question of this article, is catnip safe for your dog? If your pup decides to tear apart a cat toy (as my girl Willow has done several times), should you be worried?When discussing the safety of any substance, we need to address both the potential for toxicity and the risk of discomfort for your pup. While the latter may not be life-threatening, we all want to take steps to keep our dogs feeling comfortable!Catnip is Generally Non-Toxic to DogsFirst and foremost, you can breathe a sigh of relief if your dog has recently tested the waters with the herb. According to organizations like the ASPCA and the Pet Poison Helpline, catnip is not listed as a poisonous substance that can cause severe or life-threatening reactions in dogs. If your dog nibbles a stray leaf or manages to sample the dried herb while chewing a cat toy, there is no need to panic. The plant will not poison them.Understanding “Non-Toxic” vs. “Harmless”While catnip isn’t poisonous, that doesn’t mean your dog should be allowed to eat a whole patch. It’s crucial that dog parents understand the difference between a substance being “non-toxic” (aka not poisonous) and “harmless” or safe to eat without any consequences.The risk associated with catnip exposure centers almost entirely on gastrointestinal problems. The digestive systems of our dogs are not designed to ingest large quantities of plant matter. If they eat too much of any herb or green, including catnip, it can irritate their digestive tract.The most common side effects of eating excessive amounts of plant matter are mild and short-lived, such as temporary vomiting, diarrhea, or general stomach discomfort. Generally, your dog will start to feel better as soon as the material passes. However, if your dog passes the plants and is still showing signs of discomfort, contact your veterinarian, as there may be a bigger problem to address.The Hidden Hazard of the Toy ItselfNow that we’ve clarified that eating some catnip from chewing a cat toy isn’t going to cause any serious harm, there is a danger associated with this situation that I want to highlight. Chewing a non-edible item (like a cat toy) can lead to trouble!Catnip toys are designed to be light, fluffy, and enticing for cats. But they are not durable for a powerful canine jaw, especially if your pup is a power chewer like our two! If they ingest a chunk of stuffing, the fabric or plastic pieces, or even a whole catnip mouse (yes, it happens), it can create a serious choking hazard or, worse, a risk of life-threatening obstruction.Always supervise your dog around cat toys if they share their home with a feline sibling. Immediately take away the toys if you see your pup starting to chew on them.The Impact of Catnip on DogsWe’re all familiar with the hilarious, erratic behavior you might see from your cat after being exposed to catnip, but what about dogs? If your pup does manage to ingest a little catnip, you may be surprised. The key difference lies in the way dogs and cats process the active ingredient, nepetalactone.Unlike cats, dogs don’t get “high” on catnip. Cats possess specialized receptors, particularly in the roof of their mouth, that are sensitive to nepetalactone. This triggers a strong, euphoric response when the scent is inhaled, leading to the reaction we commonly associate with the herb.On the other hand (or paw), dogs lack these sensitive receptors. While they can smell the herb, their brains do not process the nepetalactone in a way that causes the typical stimulation. Instead, they respond when they ingest catnip (either the leaves or the dried herb). For our pups, this acts as a mild sedative or relaxant. It is the same effect that humans expect when they historically brewed catnip tea to calm their nerves or help them sleep.When consumed, catnip has a mild depressant effect on a dog’s central nervous system, helping to reduce general restlessness or anxiety. The response is often very subtle, so don’t expect your dog to suddenly collapse into a tranquil slumber. Instead, you can expect your pup to show a slight easing of tension or an increase in general calmness.While rare, it is worth noting that a very small percentage of dogs may experience the opposite, showing a mild stimulating effect. Always monitor your dog carefully during their first few exposures to see how their unique system processes the herb. If you notice increased agitation or hyperactivity, stop using it.However, for the vast majority of dogs, the primary effect is either a mild calming one or none at all.
