They are now eating great, have gained a lot of weight (have gone from about 10 oz each to over a pound), are playing, fleas are gone, they love people, and seem happy. They do still have worms even after being wormed three times. I’ve already got a call in to the rescue about that. But, my concern is about their bellies. They have hardly any fur on them. Is this normal for kittens with their background or should I be concerned? They aren’t over grooming. To be honest, I’m not sure they have ever groomed their bellies.
