Chickens addicted to cat food! Will a cat door keep them out?

[The_Chicken_Tender]

I have an outdoor cat, and we feed her at a little table outside our door (pictures attached). However, the chickens are completely addicted to the cat food! Every morning when I let them out, the entire flock makes a beeline to the back patio to get their breakfast. I take the bowl away before letting them out, but my cat needs to eat. I've tried constructing a cardboard barrier with openings small enough only to let the cat in, but the chickens somehow manage to squeeze through. Sometimes I shove my cat in there and block the holes to let her eat, but the chickens circle around frantically like they are absolutely starving and that's the only food left on the planet (trust me-it's not). They aren't even this crazy for mealworms!

My main question is, can chickens use cat flap doors? It seems like they couldn't, since they would have to push it open with their beaks. Does anyone have experience with this? Or, if anyone has another idea that could work, feel free to share!

Thanks!
