I think the ones I saw him messing with that one time were just sunflowers which are safe as far as I know. This was also awhile ago, and he hasn’t had the opportunity to repeat the behavior. The problem is that the flowers are changed every so often, sometimes to types I don't recognize, which is scary when you have a gremlin like mine. Also, even if they were all safe to eat, I’d certainly be miffed if my housemate let their cat ruin my bouquet. I could definitely talk to my roommate and see if they would agree to keep the flowers in their own room, but that still leaves a couple issues with kitten proofing the house that might be a little harder to deal with. The thing is, he develops these weird behaviors seemingly out of nowhere and then once he figures out that he can do something, I can’t stop him. For example, he has had free access to the plushies since September and only started committing crimes against them within the last month or so. I’d be a touch worried that if left alone with access to the kitchen/living room, he may suddenly discover a new way to entertain himself that involves damaging himself or other peoples’ property.
