Find out if peonies are toxic to cats, what to do if your cat eats them, and learn when peonies bloom, plus care tips for a cat-safe garden.

Hey there, fellow gardeners and cat lovers! I’m Ashley Scott, and with over 10 years of gardening experience, I’ve learned how to balance my passion for stunning blooms with keeping my furry friends safe. If you’re here, you’re probably wondering, “Are peonies poisonous to cats?” It’s a question I’ve been asked countless times, and I’m excited to dive into it with you. As someone who’s spent a decade tending to gardens across the USA, I’ve got plenty of insights—and a few stories—to share.
In this guide, I’ll answer whether peonies are safe for cats, explore what to do if your kitty gets into them, and cover some peony basics like when they’re in season and how to care for them. Whether you’re a cat parent, a gardening newbie, or both, I’ve got you covered. Let’s get started!
Are Peonies Poisonous to Cats?
Let’s cut to the chase: Yes, peonies are poisonous to cats. According to the ASPCA, peonies are toxic to cats, dogs, and even horses. The troublemaker here is a compound called paeonol, found in the plant’s bark, roots, and flowers. While peonies are a dream to grow—those big, fragrant blooms are hard to resist—they can spell trouble for curious felines.
I’ll never forget the time my neighbor’s cat, Whiskers, decided my peony bed was a snack bar. She was fine after a quick vet visit, but it was a reminder to keep my garden cat-proof!
What Happens If a Cat Eats Peonies?
If your cat munches on peonies, here’s what you might see:
- Vomiting
- Diarrhea
- Lethargy
- Excessive drooling
- Loss of appetite
In rare cases, it can get more serious, causing depression or worse. The good news? Most cats recover with prompt care. For more on pet poisoning symptoms, check out the Pet Poison Helpline.
What Should I Do If My Cat Eats Peonies?
If you catch your cat in the act, don’t panic—but act fast. Here’s my go-to plan:
- Gently remove any peony bits from their mouth.
- Call your vet or a trusted resource like the American Veterinary Medical Association for advice.
- Keep an eye on your cat for symptoms and follow the vet’s guidance.
Better safe than sorry, right? I’ve learned that a quick response can make all the difference.
How to Keep Cats Away From Peonies
Cats are nosy little explorers, so here’s how I keep mine safe:
- Plant peonies in spots they can’t reach, like behind a garden fence.
- Sprinkle citrus peels or use cat-safe repellents around the plants.
- Watch them when they’re outside—my cats love a good garden adventure!
If you’re worried, you can also explore cat-friendly plants. I’ve got some great ideas in my Pet-Safe Gardening Guide on USA Garden Hub.
Understanding Peonies: When They Shine
Peonies might pose a risk to cats, but they’re still one of my favorite flowers. Knowing when peonies are in season and when they bloom helps me enjoy them safely and plan my garden.
When Are Peonies in Season?
Peonies are in season from late spring to early summer across the USA. That’s usually late April through June, depending on where you live. In my Midwest garden, they start showing off in May, hitting peak beauty by June. Want fresh peonies for a summer event? This is your window!
When Do Peonies Bloom?
Peonies bloom for about 7-10 days, and the timing varies by type:
- Herbaceous peonies: Late spring (May-June).
- Tree peonies: Mid to late spring (April-May).
- Intersectional peonies: Somewhere in between.
I mix varieties in my garden to stretch the bloom time—it’s like a floral relay race! For more growing tips, see my How to Grow Peonies Guide.
Caring for Peonies: Timing Tips
Peonies are pretty easygoing, but they thrive with the right care. Let’s talk about when to cut back peonies and when to plant them.
When to Cut Back Peonies
After the blooms fade, cut back peonies to keep them healthy. Here’s what works for me:
- Herbaceous peonies: Wait until fall when the leaves yellow, then trim to 2-3 inches above ground.
- Tree peonies: Prune lightly in late winter, removing dead wood.
I once cut mine back too early and paid for it with fewer blooms the next year—lesson learned!
When to Plant Peonies
The best time to plant peonies is in the fall, around late September to early October. This gives the roots a head start before winter. I planted mine one crisp October day, and by spring, they were ready to dazzle. The University of Illinois Extension has solid advice on this if you want more details.
Gardening With Cats in Mind
I adore peonies, but I love my cats more. Here’s how I make my garden a safe space:
- Go for safe alternatives: Roses and sunflowers are cat-friendly and gorgeous. The Cornell University College of Veterinary Medicine has a handy list.
- Add barriers: Raised beds or fences work wonders.
- Distract them: I grow catnip in a corner—my cats can’t resist it!
One summer, I set up a “cat corner” with safe plants and toys. Now, they barely glance at my peonies!
Wrapping Up: Peonies and Cats Can Coexist
So, are peonies poisonous to cats? Yep, they are, but with some smart planning, you can enjoy these beauties without worry. Keep them out of reach, know the signs of trouble, and act fast if needed. Plus, understanding when peonies are in season, when they bloom, when to cut them back, and when to plant them lets you make the most of their charm.
