Hello how may I help you? I just adopted a cat. Will he need a lot of space in my apartment I can help you with pet advice. Did you adopt just one cat or more than one cat? Just one cat, I have a small NYC apartment Okay, typically one cat needs around 500 square feet to roam. I only have 300 square feet but lot of bookcase everywhere You can monitor the cat and see if he or she is able to be free throughout the apartment. I think may he could roam around the room on the bookcase. Lot od store area Cats do like to play on bookcases. I could probably put his litter box on one of them and a pet bed That's a good idea. The cat might enjoy that setup.
