Pet sitting with Max, Sam and Riley

Everyone was just fine this morning.  The boys stayed outside for awhile after they ate their breakfast and I cleaned out the litter box.  Max had eaten quite a bit of food so I refilled his dish and gave him fresh water.  The boys were out of water.... I've been filling the bowl about 1/2 full at night because I don't want them to drink too much.  I hope that's okay.  They certainly seem fine!  Both of them played with the tennis ball a little bit this morning although Sam is still fixated with the other toys outside. They're all really sweet and Riley seemed especially soft.  Did they get a bath recently?
