I suppose it's OK as long as the litter is changed daily.
Is having 4 cats in a 1 bedroom apt or home, OK? Update, I don't own a cat and I can't asked the cat🐈 what he/she thinks and I wouldn't stay in the same home with a English or any language talking cat! Capiche.
What is the answer from the perspective of the cat?
If the cats aren't complaining, it isn't really a problem.
If it be managed pretty well. I see no problem.
I don't think I could personally manage it; but I think it's fine as long as they are being taken care of properly .... Plenty of food & water, frequent litter changes, and medical care.
