What it does
Surprising but true: the ASPCA lists the catnip plant as toxic to cats. Most cats enjoy a sniff or a roll with no trouble; the concern is eating large amounts of the plant.
If your cat ate some
- Move your cat away from the plant and take away any pieces, including fallen leaves and petals.
- Call your vet, an emergency clinic, ASPCA Animal Poison Control ((888) 426-4435) or the Pet Poison Helpline (855-764-7661). Both poison lines are open around the clock.
- Take the plant, a photo of it or its label with you so the vet knows exactly what it is.
- Don't try to make your cat vomit unless a vet tells you to.
Cat-safe alternatives
The ASPCA lists these as non-toxic to cats. Any plant can still upset a cat's stomach if eaten in quantity, but none of these are poisonous:
