When Homer and Francine first arrived at our home, we didn't have any cat food dishes. So we fed them on our saucers. That seemed to work out fine, but I didn't want to accidentally break one of them. I invested in a stack from a thrift store. Of course several of them have broken by now, so it was time to replenish the stack.
One of them was made for Francine!
Tiny came with her own dishes and still uses them. We have served her once or twice on a saucer but she tended to nose the food right off the plate so it was back to the bowl for her.
