Hello everyone, i have a question, I have two bunnies (i don't know the breed hubby brought them home a few months ago, they are brown and white with floppy ears. male and female, they have been living in a 3x3 cage for the past few months, every once in a while I let them run around in my kid's play area a 50x50 fenced in part of our yard. there's no way for them to get out, so I'm considering just letting them live in there. there's a 4x4 metal enclosure with one side open, where I put their wooden box and their food and water bottle too, I showed them this and they are pretty much hanging around there, running around, then coming back to that area. is their any bug or safety issue that I haven't considered? hubby is concerned if she has a litter the ants might find them, or ticks might be a problem this spring.
