Both of mine like the shower door too- (tho, I close as quickly as I can) so they substitute with my legs instead. (WILLLLL You Stop that CAT!) Rasp, Rasp.
Something about the curves in this one. THe faucet. The sink bowl. The arch of the cat's neck. Cat's are friggen weird. Fresh water, right from the tap into a clean bowl...and Skillet would rather wait for me to leave the shower so he can hind leg it and lick the wet tracks of the shower door.
