Sprinkle black pepper around the base of the cat food bin. Ants will not cross a trail of black pepper. This is a trick I learned working the carnival. When we pulled onto a lot, and dropped the trailers on location, once the jack stands were down, we sprinkled pepper around them and the tires on the trailers, that way the ants couldn't/wouldn't get into the trailers but climbing up the stands or tires. When you are working with cotton candy (pure sugar)or fried bread dough (grease) or ice cream (more sugar) you'll try anything to keep out the ants. Pepper seemed to work.
It works for me here at home too. I once had a serious infestation of big black ants in my cabinets. I haven't seen a one since I sprinkled pepper on the shelves and on my windowsills. Okay, it looks a little dusty, but it works.
Maybe you could put a rim of glue around the base and glue the pepper to it?
I doubt that would work, You would have to be very careful that the glue didn't encapsulate the pepper at all. If they can't smell the pepper, it's not going to work.

That's interesting....
The ants will carry away the salt instead of the food, and slugs (which were the big problem) will die on the salt and stay out of the food.
Pepper is an interesting solution, though.
