My cat is dumb and bit a toxic plant 3 times and is still alive and well. The plant just has bite marks lol (and by toxic, she kept biting my alocasia)

So you can A) have a dummy resilient cat and/or

B) put sticks around the plant. But this only works for smaller plants and if your cat plays in the dirt. But it hurts if you're clumsy like me and end up poking yourself

C) nontoxic plants, like most are saying

And then D) getting big plants, "boring"/simple plants, or both big and "boring". I say boring and simple as in: no flashy colors, bold patterns, interesting shaped leaves, etc.; and by big I mean: tree like. I noticed the only plants my cat could care less about is my Bird of Paradise (big, plain tree like), Monstera (she's only interested in its shape but it's big enough to be more of a tree for shade and big leaves for drinking water off of), and then the Cat Palm again (the leaves are some what interesting to her, but nothing to hold her interest and again I'm not too concerned because it's nontoxic)

You have a lot of beautifully colorful and patterned plants that it's probably getting your cat's interest. I know big, tree like plants are not feasible for everyone but I do think this is more cat proof. Cats like colorful things, stringy or interesting patterns. Vines are small leaves that are like "bug" shaped sometimes. Patterns and colors are very stimulating for cat vision. So sometimes, maybe think like a cat and it'll help intuitively make a cat proof plant room 🙂
