How long did hydrolysed food take to help your cat’s skin?

Have you had a cat with a food allergy, causing the cat to over groom (bald patches and broken skin)? If so, when you changed to hyperallergic food, how quickly did their skin improve?
We have had our rescue cat for 7 months, she’s 8 years old. She came to us with no obvious skin issues. Since she’s been with us she has been overgrooming. The vet thinks it’s a food allergy (there is definitely something odd about her background with food - but the rescue weren’t clear - she would only eat wet food and there was mention of her not having been fed enough in the past - I wonder if the previous owners might have known there was an issue and not told the rescue).
On the vets advice, we have changed her to hydrolysed dry food and mono-protein Kangaroo wet food (she won’t eat the hydrolysed wet food). We are a couple of weeks in and we aren’t seeing any improvement. Google suggests it might take much longer to see improvements, but I can’t find any actual accounts from owners about this and I’m not sure it’s accurate. I wondered if anyone had any experience of having been through this?

With my cat it took steroids, cyclosporine and diet to control the over grooming. That took about 10 weeks, then I stopped the steroids. Cyclosporine I continued for 6 months. She has been controlled on just the diet for the last 8 years.
She was also a stray sadly her skin had been untreated for so long that she has an area at the base of her tail where the hair never grows fortunately as a Siberian it is not obvious.

Gosh, I think I’ve been unrealistic in my expectations of how quick this might be to resolve. I am just so worried about her and hoping for a miracle quick fix.
It’s just so odd that she was fine till she came to us, but she’s was definitely not being fed sufficiently by her previous owners and we got some slightly odd garbled info about what her previous diet was, which makes me wonder if the previous owners knew she had allergies. Anyway, we just need to figure this out before she goes bald (poor wee thing).

My cat (now passed away, bless her) struggled with allergies the whole 8 years we had her. We think hers were environmental and food allergies, she improved with diet but was never able to come off steroids. We also fed the kangaroo food (the brand we used was mjammjam) and it did take a while to notice improvements, I honestly can’t remember exactly but I want to say 4-6 weeks maybe.

Whilst the hydrolysed protein was good to begin with, I did notice it constantly going out of stock, which stressed me out each month trying to find websites where it was still in stock. There were never any supply issues with the kangaroo, so I was really pleased that suited her. Her poos were much better on the kangaroo as well.

One thing to consider is that your cat could be allergic to ANYTHING - wash powder, plug in air fresheners, houseplants, dogs, so whilst the vets can do some testing, sadly you may never get to the bottom of it.

I really sympathise with you having to go through this with your pet. When I took my cat on, knowing she had skin issues, I never imagined how hard it would be x
