cat and kitten food

Cats are individuals, just like people. They are beautiful, fascinating creatures with their own special nutritional needs and definite preferences - some like chicken, some like fish. Some cats like canned food, some like dry food, and some like a combination of the two. Keep in mind that no one food is best for every cat. You could feed a brand of very well-formulated food to a group of cats and find that most of them do great on it, some do marginally well, and a few may actually get sick from it due to food intolerances or other medical problems. Luckily, today's market offers many well-formulated cat foods for cats at all life stages, and it's fine to try several to determine which one works best for your cat.
After you've done all you can to make sure a food is healthy and beneficial, take a look at your cat after feeding the food for at least a month. Bright eyes, a shiny coat, and a healthy energy level will let you know you've chosen a good source for your cat's nutrition. If you need assistance selecting a food for your cat, seek veterinary/professional advice.
