Hello how may I help you? how much space do i need in my apartment if i wanted to get a pet cat? It appears that you should have at least one spare room for your cat to roam. how many square feet? At least 100 square feet. if i were to get 2 cats, would they be able to share that same amount of space? If the 100 square feet is dedicated to the cats only, they could share that space together successfully. could the 2 cats share the same litterbox or would i need 2 litterboxes for them? Cats are able to share a litterbox, but it is recommended to have a second litterbox to avoid territorial issues. ok great, thanks for the info! You are welcome. Anything else I can assist you with today? that was it, thank you
