So! The Runt and I went to see a specialist last night about his continued discomfort. While he had been doing better after his initial treatment for flea allergy dermatitis, he had still been occasionally scratching and digdigdigging at himself, and last weekend he took a turn for the worse.
I got the name of a cat specialist, and last night we went to see her. She seems to think that in addition to the flea allergy thing, he also has an inhaled allergy, i.e., he's allergic to something in the air, like pollen or ragweed.
The thing that was throwing me off was that he keeps acting like something's biting him. He'll be just walking across a room and he'll flinch, like something just chomped on him, and then he'll throw himself to the floor and digdigdig at himself.
The specialist vet explained that in cats, inhaled allergies can "settle" in the skin. In humans, if we're allergic to pollen or whatever, it affects our mucous membranes, so we get all congested and wheezy and teary-eyed. But in cats, it tends to make their skin itchy. And it kind of acts like hives, so that while they're itchy in general, a certain patch of skin can suddenly act up, causing them to dig madly at one spot.
I don't know. Does this sound reasonable to you? Because we started him on the steroids last night, and this morning he's still digdigdigging.
Poor guy. Send kind thoughts his way, please.
