Ellie Masters asked:
My cat is scratching above his eyes and losing fur, sometimes his eyes water too. this happened earlier in the summer he went through testing nothing found, he’s treated with stronghold so no fleas etc. All help appreciated as at wits end now
Hi again Ellie, thanks for your question!
To answer it, I’m going to discuss the possible causes, then the investigations available to demonstrate them, and then finally possible treatment options.
What possible causes are there?
Given that he’s scratching the area around his eyes, losing fur and has watery eyes, there are three immediate possibilities that spring to mind.
The first is a primary eye disease – conjunctivitis, a corneal ulcer, chlamydia or calicivirus infection are probably the four conditions I’d be wanting to rule out. In this situation, the hair loss is because of his constant rubbing at his sore eyes.
The second possibility is that it is a skin disease, manifesting most dramatically on his head above his eyes. This may sound unlikely, but many cats suffer from a condition called miliary dermatitis, where the skin becomes very itchy and forms tiny red scabs or bumps – often it is focussed above the eyes and in front of the ears, although along the back is also a possibility. This is not a diagnosis, but a symptom – and is most commonly associated with parasites, allergies, or skin infections.
The third option is a condition that affects both the skin and the eyes – classically, this would be a more general allergy of some sort. Allergies in cats are less well understood than in dogs, however, food allergies are thought to be the second most common cause of itching in cats (after fleas and other parasites). Other possibilities would include auto-immune disease, where the immune system starts attacking healthy tissues.
So, how do you tell which it is?…
