Hello, how may I help you? Hi I have a question Sure, what would you like to ask? How much space do you need in an apartment for a pet cat? You need about 400 square feet for a pet cat? Maybe 500 feet. Is that enough room to put one of those cat things they climb on? A cat home, yes it is! Is it okay if I keep my cat and my horse in the same apartment? You can also fit a litterbox in there as well as a drinking fountain. That might not be the best idea, you may have to look into that further. What if I have a cat-sized horse? I don't see a problem with that! Great, thanks!
