Having difficulty getting my girls -- longhair Torties -- to ingest Petromalt - a hairball remedy. Their diet is Royal Canin for Longhaired (kibble-like) and I try and brush/comb every day but one of them always seems to leave me a "present" in the middle of the night. I've tried putting it on a glass coaster, my fingers, on their paws, nose, but no go. The Turkish Angora our family had spoiled me in that she would come running whenever we took the tube out of the drawer and lick it off our fingers no problem! Any ideas would be appreciated. Thanks
