Following on from the kitty with chicken allergy thread....does anyone have ny idea why chicken would cause this. My cat Bear also has chicken allergy. Unyet can eat turkey forever. Ive never been able to find information as to why.Ive had bog standard chicken. Ive bought top quality free range organic local butchers chicken. Supermarket organic chicken.Latter 2 still, despite the diet they must be on, cause the dreadful itching. However weirdly 2 supermarkets have normal chicken that cause no/ minimal eventually reaction...I find that strange. So why does it happen I wonder?
