My kitty does that with her food!
My kitty, Jade-5 yrs old, does that on occasion with her food. Just the other day I caught her lying on her back/side, pulling pieces of her food out of her dish with her left paw and eating it. I laughed my butt off, wondering how lazy, tired and hungry she had to be to do that. She gave me a look like "what's so funny"? But she has issues with putting her face into her bowl... she doesn't.. instead she picks one piece out at a time, pulls it away from her dish and eats it. But usually she isn't laying down. If her water dish isn't full to the brim, she won't drink it.
Aren't all our cats silly!!
