Your cats are really fun!  Sprinkles wanted some attention right when I got there so I rubbed on him some.  Lo was over by the food dishes.  One of them was empty and the other was probably 1/2 full so I thought perhaps she wanted some fresh food and here I was just petting Sprinkles.  I filled up the food dishes and gave them fresh water.  When I finished with that and looked up, sure enough Sprinkles was sitting on the bathroom vanity.  I turned the water on and he drank the whole time I cleaned out the litter box.  While cleaning out the litter box with the lid, Lo came in and I heard this scratching sound.  Lo and behold (that was bad I know :), Lo was in the other litter box.  I didn't even see it over there so it's a good thing she got in it.  Lo and I played with the string and a couple of times Sprinkles would paw at it too.  They're doing just fine!
