Izzi is a picky eater. She eats Purina Medley Salmon Florentine with a few pieces of Blue Buffalo Kitten. Everything else she outright refuses. Just looks at it and buries it. Sometimes actually buries it by rolling a rug. She is skinny and growing. Her fur is really coming in. Yes, new pictures! Two tiny hair balls in three weeks. Cat gras is always available and gets eaten by all three. She will not eat large portions. A heaped table spoon and 5-6 kibbles and she leaves some. I offer tiny plates during the day which is not easy as ShadowCat comes out of deep sleep and wants her share. She is overweight. Has always been plump and had tendon issues for two years, UCI, ... Not to mention temper. Are there any safe supplements? I have tried egg, chicken cooked, .... Thank you!
