Pets at Home Purely, Tesco Luxury, Tesco Finest, Tesco Just Nature, Hi Life Essentials, Hi Life regular/senior, Natures's menu, Felix senior (Jaffa only), Almo Nature/Applaws/Encore, Animonda Carny, Bozita, Schmusy, Schessir, Cosma, Porta 21, Miramor.. probably a few others! Dry is Orijen or Encore usually but I will buy hi life or occasionally Purina One if money is tight.
Jaffa has wet food only as he is getting older (he's 13) and I think wet food is better for older cats due to potential kidney problems. He has also had idiopathic cystitis a couple of times. I also try to feed stuff with a high meat content and no/minimum cereals as I think that is best for an obligate carnivore. Jaffa loves raw so I give him raw meat occasionally but not often enough to worry about the nutritional aspect. He also gets raw chicken wings a couple of times a week. Jaffa likes his felix so he gets some felix senior but not every meal.
Mosi has a mix of wet and dry as he's younger and it helps to keep the costs down. He has the same wet foods as Jaffa although he has more hi life (he loves the tins of pate but they are high in phosphorus so I rarely give Jaffa that) and no felix. He has a half portion of wet food and I sprinkle a bit of dry on the top. Dry food is usually Encore from Sainsburys as it is cereal free but at the moment he is having Purina One because I was skint and it was cheap!! I buy Orijen from Zooplus sometimes too. Mosi doesn't like raw although he will eat small pieces.
I am lucky in that they will eat pretty much anything. Jaffa does occasionally give me dirty looks if he's gone off something, but he's usually happy to eat it again after a few weeks absence.
