What works for me - though cats will have dander, as their skin refreshes itself (I think we humans have dander too, but I don't wanna go there! )

I thoroughly cleaned a dropper bottle I had (it just had Stevia in it before), and put canola oil in it. You can also use olive oil (NEVER castor).

Also - Omega oil from the vet, use according to instructions.

Put ONE SINGLE drop into a small amount of wet food that Cassie will eat right up. Do this daily. Within a week you should see a change.

I use this when it's drier in the winter here and Oscar especially starts to scratch. Works like a charm.

My mom tried it on one of her cats who scratched a lot - again, success.

I know Cassie isn't itchy, but if her problem is dry skin, a wee drop of oil just might set things right!
