Hello how may I help you? I have a question about my new pet cat What would you like to know? I have a new persian cat and I was wondering how much space I need to have in my apartment for the cat. You don't need a lot of space for Persian. Average Sized entrapment would suffice. apartment Ok great. I should have plenty of room then! How many square feet is considered an average size apartment? about 600-700 SQ FT Ok great! I have much more space than that! Is there anything else that I can help you with? No thanks. That was very helpful. Thank you very much. You are welcome
