Tonight, Branden and Briggs took their first inside bath of the winter. It was actually Branden's first inside bath, ever, and you can see how super comfortable he was with the concept. He spent the entire bath either trying to escape from the bathtub (he got out three times) or standing in the far corner trying to stretch as far away from the water as possible.
I wash them frequently during the Summer to cool them off, but that is done outside, of course. It's much simpler.
