No plant is safe in our home. Here is my older cat, stripping leaves off the curry plant. I discovered several chewed up ones on the counter. Apparently the taste is not to his liking. We're having lovely summer weather, so I've moved the plant outside. I love having fresh flowers from the garden in the house, but unless they are in a small container, just a wee little flower or two, the cats will find them and chew on them. I wouldn't mind it if they didn't barf it up later, along with their food. When I'm in the kitchen, I can enjoy my flowers, but if I have to leave, I make sure they are put outside on the patio or in the bathroom (with the door closed). Ah, the things one must put up with.
Here's the other naughty cat, dipping her paws in the water that is for the Drinking Bird. I believe we were doing an experiment to see whether the temperature of the water changed the rate of dipping. It did.
