My Sweetie used to do that. There was hoods on her dishes and she would crawl into her dish and then chicken scratch to get to the good food. I think she still chicken scratches as there's still a lot of shells and whatnot kicked out of her bowl but she doesn't crawl into it as much. I would crack up every time I saw her butt sticking up in the air as she was eating. I took the hoods off the dishes since she figured out how to take them off. And now she figured out she can bathe in her water dish. At least she tries to.
Now, JoJo will sit at the edge of his stainless steel bowl and take a nap there. Sometimes he's in it.
