Anyone tried this over royal canin hp dry food? the cost is so much better, just wondering the effectiveness in comparison?

I have never tried the Royal canin hp. My vet had recommended the Purina and since breaking out in bumps all over my kitty has not eaten anything since. The allergy bumps have been gone since I started using the Purina, but it did take 3-4 months to totally clear up. I was delighted to find the Purina HA available online as my vet is about 15 miles from our home and that was the only place I could buy it before.

what are the food ingredients listed in this product

Hi, I actually went on another site to find the ingredients before I purchased. Here's the list: Rice starch, hydrolyzed soy protein isolate, partially hydrogenated canola oil preserved with TBHQ, hydrolyzed chicken liver, tricalcium phosphate, powdered cellulose, corn oil, hydrolyzed chicken, sodium bisulfate, DL-Methionine, potassium chloride, choline chloride, tetra sodium pyrophosphate, L-Lysine monohydrochloride, phosphoric acid, salt, vegetable gums (gum arabic, guar gum), taurine, lecithin, magnesium oxide, zinc sulfate, ferrous sulfate, Vitamin E supplement, manganese sulfate, niacin, calcium carbonate, citric acid, Vitamin A supplement, calcium pantothenate, thiamine mononitrate, copper sulfate, BHA (a preservative), riboflavin supplement, Vitamin B-12 supplement, pyridoxine hydrochloride, folic acid, Vitamin D-3 supplement, calcium iodate, biotin, menadione sodium bisulfite complex (source of Vitamin K activity), sodium selenite

How long does it take to show effect? Just wondering when I should notice change!

We noticed less bare spots from over grooming during the first bag.
