Houseplants Poisonous to Cats

Curiosity killed the cat, or so they say. Cats are curious creatures, they love to climb, explore, squeeze behind or into things and probably get into just as much (or more) mischief as dogs.
But with that curiosity comes some risk. Especially when they are curious about some of your houseplants. Cats naturally eat some plants – it is a source of fiber to them, but some plants can be poisonous. Reactions may vary from mild stomach ache to death, so it’s important to know which plants are safe and which you probably don’t want to have in your house if you have a curious cat.

  • Lilies: While beautiful, the can be a disaster for your pet. Symptoms typically show up 10-12 hours after ingestion and range from mild irritation around the mouth to vomiting. Left untreated could lead to kidney failure.
  • Asparagus Fern: It’s the berries of this plant that may cause problems, including stomach distress, vomiting and diarrhea.
  • Dracaena: While not lethal, the outcome of eating this plant can be scary. Your cat may vomit – sometimes with blood, become lethargic and seem drunk.
  • Aloe: There are many healing properties to the fluid inside an Aloe plant. But it is also dangerous and will lead to vomiting and reddish urine.
  • Philodendrons: This plant and other Calcium Oxalate plants contain microscopic crystals that look like needles. If eaten these needle like crystals can cause gum and mouth irritation as well as swelling.
  • ASPCA provides a comprehensive list of plants that can be harmful to your pet. If you are suspicious your cat has ingested something that is potentially harmful, call the Poison Pet Hotline immediately: (855-764-7661)

  1. My family owns a nursery, but surprisingly I don’t actually keep any plants inside of the house. Sometimes, I’ll pick a few flowers for a vase. I’ll have to be careful what I put in there now!
