Karla, I just had a thought: (amazing, I know!), but do you think she could be off her feed because her mouth hurts? I mean, she did have a big oral surgery, and animals DO feel pain just like we do! Is she on pain meds? If not, you can give her one aspirin a day. That will help with the stiffness too. Hugs and kisses for the furbabies! And you too. I know how hard it is to watch one of our dear friends get old.
