A cat that enjoys a fish-led meal may still care about the smaller ingredient beside the tuna. Here, crab provides the distinction, while the broth keeps the recipe firmly in the wet-food aisle.

Applaws Tuna Fillet with Crab in Broth is a complementary cat food in a 70g can. It contains tuna fillet 55%, fish broth, crab 5% and rice. The analysis gives protein 13%, crude fat 1%, crude fibre 0.1%, crude ash 1% and moisture 83%. The label also gives 701 kcal/kg and 49.1 kcal/can, and states no additives.

The key dietary limit. This is complementary rather than complete, so it isn't a whole diet. Applaws says to feed it with its complete dry cat food for a balanced diet, up to 2 cans a day depending on the cat's size, served at room temperature, with fresh drinking water always available.

Who it's for: cat owners who want a tuna-and-crab wet food to use alongside a complete diet, with the percentages, calories and additive status stated plainly.
