I feel your pain!

My husband had a Doberman who never ate dog food, and lived to 15 years old, which is old for a Dobbie. He actually fed her anything he ate, meat, veggies, salads etc. Now he thinks the cats should also eat people food, including at the table. Of course, at the same time, he complains that he can't eat without them bothering him! It is an ongoing battle, but he has agreed not to feed the kittens "people" food! yeah, a partial victory!
It is really important to make our guys understand it is to everyone's benefit to set limits and stick to them!!
Good luck!
