Hi everyone,
We adopted our little girl from the RSPCA back in 2018; she was a young cat (2 years old) full of life and very playful. Since we got her, we’ve been giving her Credelio every 6-8 weeks on average to protect against fleas and ticks, plus a wormer four times a year. In the summer of 2019, for no clear reason, she started licking herself compulsively and her lower belly ended up completely bald. The vet gave us a soothing cream which wasn't very effective. Even so, her fur grew back over the following months and it seemed like it was just a one-off bad patch.
Unfortunately, for four years now, our poor kitty has been going through episodes where she hides away (under furniture, on top of the fridge, in a wardrobe...), scratches and licks herself aggressively and almost non-stop for hours. Her belly is completely bald, as is the underside of her legs and her right flank. Sometimes red patches appear, though that hasn't happened since she's been on regular steroids. On top of that, her left eye weeps slightly, there’s visible dandruff in what’s left of her coat, and black 'specks' surround her where she hides. I've checked and they seem to be scabs, not flea dirt. Of course, we've been to the vet countless times (maybe 30?), and she's had several treatments: medicated ear drops when her scratching caused ear infections, steroid tablets, then long-acting steroid injections... It’s this last treatment that finally seems most effective, as it’s given her some respite, and for about 9 months now the episodes where she hides and 'gives up' have been rare. We're feeding her z/d dry food just in case she has an allergy. She still seems constantly on edge, though, jumping at the slightest thing, and sometimes she seems like she doesn't sleep for days on end. She hasn't been outside for several years now.
We're due to see a veterinary dermatologist in the coming weeks for further tests (likely a biopsy), but I was wondering if any of you have been through something similar?
Thanks.

Hello, I'm a vet student. What you're describing sounds like very severe pruritus (itching) and shouldn't be written off as just a stress-related issue right away, even if anxiety can make the flare-ups worse. So-called psychogenic alopecia remains a 'diagnosis of exclusion'.
One important point: Credelio only lasts for one month in cats. Administering it every six to eight weeks leaves a window where they aren't sufficiently protected, and a flea allergy can cause major itching without you necessarily seeing any fleas. You should talk to your vet about a strict monthly protection plan, potentially for all pets in the household, as well as treating your home environment.
Black scabs, dandruff, ear infections, and bald patches can also be seen with other parasites, skin infections, or food and environmental allergies. A dermatologist will be able to systematically organise the necessary tests: cytology, skin scrapings, fungal or parasite checks, and a proper, strict elimination diet. A biopsy might be recommended, but it isn't always the first test to be done, nor is it always enough to identify an allergy.
Repeated steroid injections can provide genuine relief, but they only manage the symptoms without identifying the underlying cause, and they carry long-term risks, particularly regarding infections and metabolic issues. Their frequency and monitoring should therefore be discussed with the specialist.
Booking a dermatology appointment is definitely the right step. Bring the exact dates of all previous treatments, photos taken during flare-ups, and, if possible, some of the black specks in a small container so they can be examined under the microscope.
Best regards,
Romane
