Poor Leo! It is likely he has serious periodontal disease if he lost teeth. Dental disease can affect appetite because it simply hurts when he eats. There could also be infection and inflammation compounding the problem. Have Leo rechecked by your vet (or a different vet) and ask him/her to do an oral exam. Leo may need a dental cleaning and could have more teeth extracted if necessary. This will require general anesthesia and dental xrays. Discuss treatment options and the procedure with the veterinarian.,

    Hello, I'm glad you're keeping an eye on Leo's eating and weight. It is never normal for a cat to eat notably less to the point of weight loss. I will often see outdoor cats who eat less cat food in the summer months because they are hunting to supplement their diet - but in those cases, the cats are keeping a steady weight. If Leo is losing weight and eating less, he should be seen by a vet. Your vet will likely want to check a fecal sample to look for intestinal parasites, and may recommend bloodwork and/or x-rays for more information. Hope this helps!
