I have 4, soon to be 5. We have had 5 at the same time previously hence why we feel something is missing with 4! We like having 5 cats although I wouldn’t rule out adding a 6th when we move into a bigger place. Where we are currently I think it’s 1 cat per the amount of rooms available. But I think 6 is my absolute maximum because of spending equal amounts of time with each/worrying about health problems etc. So how many do you have & what’s your maximum?! I have tried to add a poll. Hopefully it works. I only know a couple of people who could tick the 15+ or 20+ selections!
