My cat was licking her fur off until getting bald spots, turns out after she was taken off chicken for 8 weeks it grew back, was a allergy to chicken. However when all this was going on the vet did a skin scrape to test, that was about 7 months ago and the area she scraped is bald, am I to assume if the fur was ever going to grow back it would of by now? It is just a shame because it is in a very noticeable spot.
