I have two cats, one has a hairball problem the other a weight problem. Theey are both on Iams food, one is on hairball control and the other on weight control. Recently the one on hairball control has this on going scab under her chin, she does not scratch it but she has hair missing from the ares when the scabs grow. My other cat has massive dandruff and has all these scabs (like a collar) arooung her neck and is very itchy. My cats are 8 and 9 and do not goto to the vet, they are both indoor cats. What do you suggest it is or I do? I was thinking of sending the fat (
) one to a groomers and put peroxide on the hairball puker. Thank you Angela
