Mika has been on prednisolone for almost two weeks now. I have been feeding wet and dry food to her, giving her more of whatever she wants to eat. We’re averaging around 180-200 calories daily. She also gets treats after she takes her medicine. For those of you who have had to put weight on a cat, how long did it take? I’m so confused by the fact Mika isn’t gaining any weight. You would think she would have put on SOMETHING. Is it possible she could just stay this weight (5.5 lbs) for the rest of her life?
