Compare cans and pouches by the actual recipe, portion size and pack count. Check whether a multipack contains one recipe or a selection, and read the ingredients for the individual varieties.
Use the life-stage information on the selected product rather than assuming every wet food suits kittens, adults and seniors alike. Read its nutritional classification and feeding guide; a wet format alone does not establish that every recipe has the same feeding role.
Follow the selected recipe's serving and opened-pack storage directions. If combining foods, check the relevant mixed-feeding information or ask your vet for an individual plan rather than using a category-wide portion rule.
