Many of the better quality foods are german. Not sure why but there are few foods available in UK shops that meet my criteria. I believe European standards for pet food are very high. Happy Kitty Company foods now make up the bulk of what I feed (german foods again) but I do like to buy from more than one place. Don't want to become reliant on one company in case it goes bust and I can't find the foods elsewhere. So its HKC, zooplus and some from PAH for me. I buy Applaws/Encore and Tesco Finest from supermarket.
I have today purchased a dry food in pets at home called Aatu. It's single protein source which I like and 85% meat. expensive but I feed such a small amount of dry that it's not really a problem. They do a duck one which is good for me as I'm trying to avoid common allergens (beef, fish and chicken) with Mosi at the moment.
