I have five and I wouldn't trade one of them. But we'll eventually be back down to 3 and that's where we'll keep it. Three for us was a really good number. They seemed to chill or play in rotating groups of two, which left the other one to get individual attention. It seemed like no one felt left out.

It's like FizzGigg's Mom says there is more food going in, more vet expense and more potty time, but it's was good trade off to me - more to love.
