Funnily enough I have found male cats to be much more easy going than females. They are cheaper to desex, and as long as you do that before they reach sexual maturity (6-7 months) than they are easy as pie. We had a male cat and he rocked, he lounged around and was an indoor cat. He played with our dogs and was easy going.

Its much more responsible for the environment to have indoor cats and if you want get a cat run. We decided when we buy a house we will get a cat run out a bedroom window so the cat can wonder out and in as it wishes and we can close it at night in winter to keep the cold air out.
