No matter how tempting they might be, you can train your cat to leave them alone.

It’s impossible to explain to a cat that the beautiful new palm tree in a stunning ceramic pot in the living room is not a litter box.

Houseplants Poisonous to Cats — Cats can’t help but be curious about houseplants; they’re a one-stop scratching, playing, pooping center.

A cat sees soil and can’t resist the temptation to scratch around in the dirt, flicking it all over the floor and then proceeding to pee or poop. It’s instinctive behavior. To the make matters worse, the trunk of the plant is “interpreted” to be a scratching post. And the palm fronds? Well, from a feline perspective, they are designed for batting around and playing with because they “respond” by moving.

You need to keep your cats out of your houseplants for two reasons: 1) to prevent messes and their associated bad smells; and 2) to keep your cats safe and healthy—many houseplants are toxic to pets. Silk plants are not always the answer because some cats will still play with them and attempt to chew on them, too.

It’s essential that you let your cat know that all your indoor houseplants—irrespective of size—are a No Cat Zone right from the very beginning. Ordinary kitchen ground white pepper is your new best friend. If you sprinkle the soil area of the pot and the lower leaves, you cat will come, sniff, sneeze—and leave it alone.

If your cat persists with her digging adventures, consider placing small decorative stones to mask the soil in your pots. Don’t go for anything too small as some cats may be tempted play and swallow them. If your kitty is still showing interest, place a layer of chicken wire over the soil and then place the stones on top of it.

When it comes to stopping your cat from playing with the leaves, consider spraying some nontoxic bitter aloes onto them. This is the same product used to stop nail biting and is available from pharmacies.

You can also divert her attention away from your decorative foliage by giving her a little container of fresh catnip or wheat grass placed strategically near her water or food bowl. This should satisfy her craving for edible greenery and keep your houseplants intact.

Finally, when you are shopping for houseplants, keep in mind that some favorites, such as orchids and African violets, are nontoxic and a safer bet—just in case your cat attempts to nibble….
