I snapped these pictures of Louie playing with the cat this morning and I couldn't resist sharing them with everyone. I don't know if you can tell but while Louie is trying to play with the cat, Puddles(the cat) is trying to groom Louie.
The whole time Louie is jumping around trying to wrestle with the cat, Puddles is trying to hold him still so he can lick him. The cat will actually stick his paw in Louie's mouth for him to chew on while he grooms him! That is what he is doing in the last two pictures. They play like this all the time, and it is so funny because Louie just doesn't get it.
