I'm from Manchester in the UK and I feed the following
Natures Menu - Pets at Home, Jollyes.
Hi Life Essentials - Asda, PAH (I think).
Hi Life Pouches - most supermarkets
Bozita - Zooplus
Animonda - Zooplus
Tesco Finest - Tesco
Tesco Luxury - Tesco
Applaws - PAH, local pet shop, zooplus
Almo Nature - local pet shop, zooplus
Nature's Harvest - PAH
Schmusy - Zooplus
Eagle Pack - Zooplus
Cosma - Zooplus
Porta 21 - Zooplus
Miamor - Zooplus
Encore - Sainsburys (new food identical to Applaws/Almo Nature - I have only seen it in Sainsburys so far)
Felix Senior - any supermarket
Supermarkets over here sell mostly whiskas type stuff - low meat content and not great quality
The small amount of dry food I feed is usually Orijen from Zooplus, but if I can't get that it's Hi Life dry (Waitrose, Wilkinsons) or James Wellbeloved (PAH).
As you can see, I get a lot of stuff from Zooplushttp://www.zooplus.co.uk/shop/cats/c...t_food_poucheshttp://www.petsathome.com/http://www.naturesmenu.co.uk/products/pouches/cats/http://www.mpmproducts.co.uk/applaws...s&page=applaws
ETA - I feed what I feed because they all have a fairly high meat content, few grains and no artifiial colours etc. Some do contain by products but I'm ok with feeding those in some foods, esp as europe has tougher guidelines for what goes into pet food than the US. Supermarkets over here generally sell stuff like Whiskas, Go Cat etc which has a very low meat content. Many are bringing out premium ranges now though.
