Hello. I have a 15 year old cat that is still very active and loves to play. The only problem is he no longer eats dry food and you can feel every bone in his body. It's heart breaking to pick him up and pet him. I'm afraid I'm going to hurt him. My family and I are afraid to take him to the doctor. We have already lost 2 cats in the past 3 years due to sudden illness. I can't bear to lose another one. Any suggestions? Any ideas how to help him put on some weight. I'm truly desperate. Thank you so much for any suggestions.
