I don't know how to describe this very well so bare with me.

What I'm thinking is a platform off the ground, enclosed with chicken wire over and around the station, this way the birds would not be able to pick at the food. Make it like a have a heart trap but the cats would be able to get up on top of the table (by jumping up on it) and be able to get back out of the station by going the way they came in.

I don't know how well that was with describing it so I will try to find some examples and send them to you. --- Meg
