The second question would be whether you prefer a complete, single or supplementary food. A complete food should already contain all the nutrients your cat needs. In contrast, a single food consists of only one component at a time, such as meat.
Vitamins and minerals would be missing. Supplementary food is used, for example, to feed unsaturated fatty acids or similar. The choice is therefore already large before you have to decide on a manufacturer.
It is true that complete feeds are sufficient, but individual feeds or supplementary feeds, for example in the form of treats, should be fed. However, they should not exceed 20% of the daily ration. This variation in the diet serves the health of the cat and its digestive tract.
Variety keeps the digestive system active and fit, so that if something doesn't go down well, there is a healthy, biodiverse fauna in the cat's intestine. It also makes sense to offer individual foods, as most complete foods contain artificial supplements or vegetable energy sources, such as maize or cereals, which add to their nutritional value.
The digestibility of feed ingredients is always highest when they are as "fresh" as possible. A good example is the vitamins and minerals contained in meat, offal and bones.
