My cat is 10, I’ve noticed recently that she has a lot of dandruff along her back. She is a bit overweight and I know that can be an issue if she can’t reach to groom herself, I find it difficult to monitor her food intake as I have 3 cats, I put dry food down and they all just take turns at eating 🙈 is there anything I can feed her to try and improve her skin? Or do I need to take her to a vet right away?
