This question is a little out-there but my current vet I'm sure has the wrong diagnosis for my cat.
Many years ago when my cats were about a year old they broke out in scabbing over their face, especially over their nose, above the eyes and on their ears. Samples were sent to the Royal Veterinary College of London when the vet at the time had no idea what it was. It turned out to be a rare hereditary autoimmune disease where their immune system works overtime and starts damaging healthy cells (which is where the scabbing over their face comes in). In one of my cats, she even had swollen paws and could barely walk.
The solution was to give them steroids to suppress their over-active immune system and this worked almost instantly. You could see an improvement the day after the first tablet.
It's rare that an outbreak occurs once it's under control. They've been weaned off the steroids many years ago and have been fine. My male cat only recently got another outbreak and I've changed vets since then. The vet that's currently seeing him is useless. He's got the disease all wrong and thinks it's feline aids even though we've told him it's not (the correct disease is even on his file!). He seems to think that suppressing the immune system isn't going to work (with feline aids the immunity is low but as I've told the vet a million times, it's not aids).
Finally, after the third journey to the vet I felt like I had to bully the vet into giving steroids to my cat. I even said I'll sign a disclaimer, I just want my cat better. It's so frustrating when you know what's wrong with your pet but the vet is adamant it's not that disease and refuses to treat it. My cat now has a high temperature and is very very lethargic and overall just giving up. I had to tell the vet that my cat will die from it if left untreated. He should have known that himself.
If you managed to get through all that rambling, my question is: what is this hereditary autoimmune disease called? I've Googled every key word I can think of but I can't find anything and I can't remember what the original vet said since that was over fourteen years ago. I'd really just like to actually tell my current vet what the disease is next time I go back for more steroids.
Thanks for any help.
