For homes with curious cats
Plants that won’t harm your cat —
backed by ASPCA data.
Every plant on this page is on the ASPCA’s non-toxic list. We don’t guess. We don’t round up. If it’s here, your cat can chew it without an emergency vet visit — and we tell you which common plants to avoid.
Pet-safety claims need ASPCA-grade evidence, not blog-style guesses. The 10 plants below all appear on the ASPCA’s published non-toxic list for cats — the same list used by veterinary toxicologists and ASPCA Poison Control. We cross-reference every recommendation against that list. If you’re unsure about a plant we don’t cover, snap a photo into Growli and we’ll pull the ASPCA record before you bring it home.

Lilies (Lilium, Hemerocallis) are the highest-risk plant for cats — even a small amount can cause kidney failure. Pothos, monstera, peace lily, philodendron, dieffenbachia, and ZZ plant all contain calcium oxalate crystals that cause painful oral irritation if chewed. Snake plant is mildly toxic. If a curious cat chews any of these, contact ASPCA Poison Control on (888) 426-4435 or your vet immediately. The 10 plants below are the safer alternatives.
Plants we recommend for you
Spider plant
The most cat-resilient option. ASPCA-non-toxic, produces baby plants you can propagate.
Parlor palm
ASPCA-non-toxic palm. Tolerates low light and small pots — perfect for cat-friendly homes.
Cast-iron plant
Almost impossible to kill, ASPCA-non-toxic. Low-light tolerant and slow-growing.
Peperomia
Compact, ASPCA-non-toxic, fits on a desk or shelf. Many cultivars to choose from.
Calathea
High visual impact, ASPCA-non-toxic. Wants humidity — works in a bathroom.
Prayer plant
Folds leaves at night, ASPCA-non-toxic. Loves humidity and indirect light.
Christmas cactus
ASPCA-non-toxic, blooms in winter, drought-tolerant. Easy to share with cuttings.
Hoya
Wax-plant trailer, ASPCA-non-toxic. Slow but rewarding — fragrant flowers when mature.

What to ask Growli first
These are the conversation starters that get the most useful answers for your situation. Open the app and tap the chat bubble.
1. "Is this plant safe for my cat?"
Snap a photo or type the plant name. Growli cross-checks the ASPCA toxic and non-toxic lists and tells you the answer — with the ASPCA citation visible.
2. "My cat chewed [plant name]. What now?"
Growli triages: if the plant is ASPCA non-toxic, mild GI upset is the worst-case. If it’s toxic, we’ll tell you to call ASPCA Poison Control on (888) 426-4435 immediately and link symptoms to watch for.
3. "Why are pothos / monstera / peace lily toxic?"
Most popular trailing houseplants contain calcium oxalate crystals — when chewed, they cause oral burning, drooling, and swelling. Lilies are far worse: even pollen can cause kidney failure in cats. Growli explains the mechanism plant by plant.
4. "Are succulents safe for cats?"
Some are, some aren’t. Haworthia, echeveria, and Christmas cactus are ASPCA-non-toxic. Aloe vera, jade plant, kalanchoe, and string-of-pearls are toxic. Growli pulls the ASPCA record on any succulent species before you buy.
Frequently asked questions
+Which houseplants are toxic to cats?
The most common toxic houseplants for cats are lilies (Lilium, Hemerocallis — high risk, can cause kidney failure), pothos, philodendron, monstera, peace lily, dieffenbachia, ZZ plant, snake plant, sago palm, aloe vera, kalanchoe, and jade plant. Lilies are the most dangerous — even pollen exposure can be fatal. Always check the ASPCA toxic plant list before bringing a new plant home.
+What plants are 100% safe for cats?
No plant is 100% safe — even non-toxic plants can cause mild GI upset (vomiting, diarrhea) if a cat eats large amounts, and pesticide residue on any leaf is a hazard. But the 10 plants on this page are all on the ASPCA non-toxic list, meaning they do not cause systemic poisoning if chewed. Spider plant, parlor palm, and cast-iron plant are the most chew-tolerant.
+What if my cat chews a non-toxic plant?
Mild vomiting or diarrhea is possible — fibrous leaves and palm fronds can irritate a feline stomach even when chemically safe. Monitor for 24 hours and call your vet if vomiting persists. The plant itself won’t cause poisoning, but a chewing habit suggests your cat needs more enrichment — try cat grass (oat or wheat) and silver-vine toys.
+Why is monstera, peace lily, or pothos toxic to cats?
All three contain microscopic calcium oxalate crystals (raphides) in their leaves and stems. When chewed, the crystals release and pierce the soft tissue of the mouth, tongue, and throat — causing intense burning, drooling, swelling, and difficulty swallowing. Systemic poisoning is rare but possible if a cat ingests a large amount. The ASPCA Poison Control hotline (888-426-4435) can advise on next steps.
+Are lilies really that dangerous to cats?
Yes. True lilies (Lilium and Hemerocallis species — including Easter lily, Asiatic lily, tiger lily, daylily) cause acute kidney failure in cats from any exposure — eating a leaf, drinking vase water, even brushing against pollen and then grooming. Without prompt veterinary treatment, lily exposure is often fatal. The ASPCA recommends keeping all true lilies out of homes with cats entirely.
+Are succulents safe for cats?
It depends on the species. ASPCA-non-toxic succulents include haworthia, echeveria, sedum, lithops, and Christmas cactus (technically an epiphytic cactus). Toxic succulents include aloe vera, jade plant, kalanchoe, string-of-pearls, and snake plant. Always look up the specific species on the ASPCA list — "succulent" is not a category that maps cleanly to safety.
