I am looking at getting some pet rabbits and I want to keep them outside. A lot of the cages that I have seen for outside have tops on them. I was just wanting to fence off a section in my yard to put them in. They would have a house to go into at night but the whole area itself wouldn't have a top. We don't have any coyotes or anything but we do have raccoons. Will they get in at night and bother the bunnies. I have a dog that stays in the backyard but we is very good with small animals and I think would keep out most other animals. So is it a good idea or not?
