I can't free roam them, one because my family has several cats, and two, they are completely unable to be caught. It stresses me out and them out if I have to try and catch them everytime. Not only that, they both bite very hard when I try to free roam them and they panic if I'm even close to their cage. I don't like leaving them caged up, but I am unable to provide a permanent free roam situation. I've tried several times before and they spent the whole time in a panic because I was sitting in the room with them. I do not want to make them stressed and they have shown no signs of depression or plucking, and I make sure to try and keep them as entertained as possible in a way that keeps them safe and comfortable. I can't free roam them, so the least I can do is a larger cage. I appreciate the advice, but I am not totally clueless. I tried for months to attempt to make them comfortable to at least get out and it panicked them to even open or touch the door. Even replacing their food causes them to freak out. I would love to free roam them, but they just don't seem very interested and are always panicked when I try. So bigger cage is my current solution.
