Stopped by the vet after work Friday and got a suppliment to add to her food. She seems to like the taste (so far, so good).

Livvy is very shy of water, so I've hestitated washing her. The vet suggested a dry shampoo. (After severe warnings about not using one formulated for humans on her...)

I'll let you know how it all goes, but it seems to be helping after just a couple days! Let's hope it continues improving.
