Hello how may I help you? I have a cat, how much space will he need in my apartment? About 700 Square feet should be fine it's a pretty big cat How big is it? she weights 55 pounds and still growing It's a tiger Then maybe you need to build and enclosure for the tiger outside I live in a city apartment can I keep her in the bathroom? I don't think tigers will live well in that small area it's a big bathroom, 17x17 feet That's probably okay then thanks You are welcome
