I never new people put cats in cages or made them live inside that is so wrong I would never own one if I had to do that. I have two at the moment one of them is 18 and the other three we lost our 15 year to cancer three years ago. Just can't imagine there lives if they were confined. We have even taken the two older ones camping and on different holidays, still just letting them come and go as they pleased. I suppose if I could make a quarter acre cage I would be happy with that.
