just wanted to post, Patches is better. no more shaking his head, or sneezing. the wax never was dark, and was gone soon.
I think all the times I thought he had a hairball, it was allergies, and the same with Cassie, she does that open mouth breathing thing, and the last couple days she has done it 4 or 5 times. it's awful to see her do that. I will have to take her to the vet if she keeps doing it. those 2 cats sure have allergy problems.
