I'm not specifically allergic, but I noticed that I was becoming more and more sensitive over the years (detergent, softener, etc ...). Even with detergents saying-or hypo-allergenic I ended up suffering from severe itching ... until I test Cat - Sensitive. Because I must say that since I use it, finished scratching, hello comfort. I hope it will last and for now it crushes by far all the others, this is the one I tolerate the longest! In addition with the program "save by subscribing your" I do not even have to think about it, I'm always in stock, it's really great.
