I don't have any cats myself, but Zakura's brother apparently thought he was one and used his family's cats as jumping obstacles:roll: (Where he is now or if he still shares home with cats I'm not sure. They gave him away because he was aggressive...even though I advised them to get him neutered, since I had the same problem with Zakura and she turned out okay)
My neighbors also have a cat who likes to stay in with their rabbits, and occasionally even mine
Don't have pics of them being "together" since my buns are "locked up" most of the time:lol: But I have seen him get into Zakura's run once, but he ran of so fast I couldn't get a picture of it.
Here he is checking out Aroma and her babies, Tobi and Rufus.
Pumba (the cat) didn't try to get in, he just sat there staring at them for the longest time:roll: Perhaps he thought Aroma would get overprotective if he came in, I guess she could... Never heard of a cat killing adult rabbits but babies are definitely at risk.
Here's one of their first meetings. Before Tobi and Rufus were born.
