When keeping pets that live in terrariums or aquariums, it's common to consider the minimum amount of space they need in their enclosure in order for the animal to be happy.
I was wondering if there was a similar kind of guideline for cats?
I did find it mentioned in The Cat Fancier's Association website that their minimum size of a cattery for a single, 4 pound, cat is 30 square feet.
Is there a guideline for how much space a cat needs to have if keeping them in a house/apartment?
