We're going to be adopting a cat or most likely 2 cats when we get back from vacation in a couple weeks and we have lots of questions before we get them since both me and my husband haven't had a cat in a long time. We have a bay window that faces South (and faces a couple bird feeders that I bet cats would love to watch). It's been a perfect place to grow cactus. We're wondering if we can just move the cactus to the corners of the bay windows giving the cats space to lay up there. Do you think they'll knock over the cactus or worse yet hurt themselves on them or try eating them?
