We give Jasper a little bit of canned pumpkin, about 1/2 teaspoon or less at a time. Our vet suggested pumpkin for the fiber effects years ago before he was diagnosed diabetic. The pumpkin can says its 4% carbs so I think a little bit is still ok. If you try pumpkin be sure to to get 100% pure pumpkin, not pie filling. Give Baby just a little to see how it takes effect.
Switching from all dry food to all wet food has really increased hairballs with 3 of our 4 cats, so we also try to brush them more when we can.
