I have two of them, one is about 6", would that be the small? The other is probably about 10" tall. Ruby and Reno are each under 4lbs and play with both sizes. The squirrels for the larger one aren't too big for them to carry and run with either.....also it is kind of fun to watch Reno, stick his head inside the larger one to get the squirrels
. I don't know if his head will fit in the smaller one.
