Basics of Kalanchoe

Popular as an indoor plant, kalanchoe is a flowering plant that's relatively low maintenance. The plentiful, tiny blooms on these plants can be red, pink, magenta, yellow, white, or orange, making them a bright addition to a sunny spot in your home. There are many types of kalanchoes available, but these succulents typically have thick, waxy leaves displaying scalloped edges.

Symptoms of Ingestion in Cats

Kalanchoe is considered mildly toxic to cats and dogs. The toxicity in kalanchoe plants comes from bufadienolides, which is a cardiac toxin. The most common signs if your cat or dog nibbles on the plant are gastrointestinal, including vomiting and diarrhea. Ingesting large amounts of a kalanchoe plant could cause an abnormal heart rhythm or rate, although this side effect is rare. Your pet could also become weak or collapse after eating large amounts of kalanchoe.

How to Respond to Ingestion

If your curious cat takes a sample of your kalanchoe and shows signs of sickness, remove the plant from your pet's mouth if they didn't swallow it yet. Keep the part of the plant in case you need to take your cat to the vet so you can have a sample of the plant they ate. Even if your pet doesn't show symptoms immediately, keep an eye on them to watch for a delayed reaction.

Keeping Your Cat Safe

It's a good idea to check all of your houseplants to see if they're safe for your pets. If you want to eliminate all risk of sickness, getting rid of the toxic houseplants is necessary. Replace them with plants that aren't toxic to cats, including Boston fern (​Nephrolepis exalta bostoniensis​), burro's tail (​Sedum morganianum​), or polka dot plant (​Hypoestes phyllostachya​).

If you want to keep your plants, place them where they're difficult for your pets to reach. This can be challenging with cats, as they tend to climb or jump their way to nearly any height in your home. Offer your pet lots of toys, a cat tree, or other stimulating activities that keep them busy to discourage them from messing with your plants. You can also grow plants that your cat can eat, like catnip (​Nepeta cataria​) or wheatgrass (​Triticum aestivum​), and place them in an easily accessible place to keep your cat from eating your kalanchoe.
