In the few months prior to her dental surgery she had slowly lost weight. Jag had always been on the plump side, for a feral. My goal since her surgery has to get some meat on her bones to help her survive winter more comfortably. All was going well until early August when, looking back, I realized there had been some subtle changes. She no longer greeted me when I arrived to feed, she was eating less and she was shying away from me. I kept a close eye on her for a few days and decided she might have an infection from the surgery. I put her on antibiotics for almost 3 weeks. Slowly she has improved. And she has been coming out to greet me, almost to the parking lot some days. She hasn't done that since summer 2012.
Yesterday I went to the vet's office to buy a special food with extra calories for Jag. She ate the entire can with gusto this morning. After her tummy was full she went into the sleeping shelter for a nap. On my way home I stopped at the vet to pick up a few more cans.
I think she will be okay.
