My cats are driving me crazy!!

Maybe not crazy, but I'm heading in the direction of the nearest poorhouse for sure.

I have two kittens who have the habit of licking up all the gravy from the food I give them and then just walking away. (Actually they're 1.5 years old.) Does anyone have a solution to this problem? It's not an unusual one, I understand.

At least twice a day I have the disgusting task of throwing away the meaty bits they don't eat.

Any advice would be appreciated.
