The plants take quite a beating from the monkeys when they come in for the Winter time. I stock up on "Bitter Apple' spray and spritz down plants that the cats are fond of chewing. I know philodendrons are toxic, and I have a huge "Fiddle leaf philodendron" that is like a toy for the cats. Never seen them chew on it, but don't want to risk it either! My most abused plant is my ficus tree. The truck becomes a scratching post all winter, and protecting it from multiple claws is near impossible.
