quick update - I was starting to freak out that Tilly hadn't had real food in like two days, so I mixed in some canned with some dry. She gobbled down about a 3rd of a cup. I'm wondering if she has problems with her teeth? It's like she doens't want to chew the dry food. When she's finished washing her face, I'll check her teeth and see what might be happening. I'm going to call the vet tomorrow regradless.. either way I think she should be checked.
