I have spent 8 years resolutely keeping the cats off the worktops, and our kitchen isn't very big so no place for the cat bowls except the floor.
Puppy seems to love their food
and is at their biscuits whenever he goes in the kitchen [which I do try to keep him out of as much as possible but he has to go through there to the garden, and it's not always practical to keep the door shut]; mind you, the cats jump at any chance to go in his pen and nick his food in return, usually when he's out in the garden...
Will he grow out of it [am thinking not likely] or should I just resign myself to having cats with glossy coats and a dog with no hairballs? I guess I'm more concerned it may be actually doing them harm eating food formulated for a different species?
