I can’t trust our cat — He’s never done anything to my bunnies, but my gut says he would play too rough as he likes to catch our pants with his paws, or if we drop spaghetti noodles on the kitchen floor, they are done for. Just anything that moves, he wants to bat around. We also have a gate and though he has never jumped over that to get to the bunny room, I still don’t trust it. I have a curtain that blocks the area visually (hangs on the other side of the gate away from him so he doesn’t feel the need to play with the curtain. The curtain is also secured with velcro. For whatever reason, that completely negates our cats interest in the bunny room. However, if I have to leave the house completely, then I do keep him separated by a by a door. Again, our cat has never done anything to show he would harm my bunnies, but I too have seen “playful” cat scratches cause eye damage and abscesses in bunnies before.
