Hello how may I help you? help me with pets I'd be happy to. What do you need help with? i got a cat in my apartment. how much space do i need? Cats don't require that much space. How big is your apartment? i have about 900 square foot in the apartment That is plenty of room for a cat! Does your cat seem unhappy? he is not moving around much That's not uncommon for a cat. Sometimes they are pretty lazy. Unless you have a health concern about him, it's probably fine thanks so much for the info! You're very welcome!
