Unlike dogs, cats must eat fresh food at all times. Cats do not have the metabolic means to digest "ripe" food and get rid of any toxins. They have evolved a very specific taste and scent capabilities that would prevent them from eating anything that is not fresh. This in part is what accounts for the "pickiness" of cats. It can be frozen first and then defrosted but cats should not be fed any 'old' meat—save that for the dogs.
Cats must eat every day. It is not wise to fast a cat for more than 24 hours. Due to their unique metabolism, cats can suffer from 'hepatic lipidosis' or fatty liver if they do not receive adequate amounts of food which can be deadly. When switching a cat to a raw diet one must be very careful that the cat eats something every day, even if that means mixing commercial food in with the raw food.
Cats do not have the capability to create taurine from other building block amino acids like dogs do. This means that a cat must ingest sufficient taurine in order to meet their requirements. The excellent news is that taurine is found in virtually all meats, especially beef heart and chicken necks. Too little taurine can weaken the heart's lining and lead to heart failure. A lack of taurine in your cat's diet may also contribute to tooth decay and blindness caused by retinal degeneration. The typical cat needs roughly 75mg-100mg per day. Because taurine is processed easily through the kidneys and passes out of your cat's system quickly you do not have to worry about overfeeding your cat taurine rich foods. By feeding a cat a raw diet they should receive the best most bioavailable form of taurine via its food.
Cats can eat the same raw foods a dog can eat, just in smaller portions and always fresh. They can eat chicken, lamb, beef, pork, turkey, duck, fish, goat, mice, eggs, and various organ meats. As with feeding dogs you should try and re-create the whole prey your cat would be eating in the wild. Some cats change their minds about certain meats once they start eating fresh raw food. The trick is to keep offering it in various. Beef liver and beef heart are excellent sources of nutrients so it is important that your cat learn to eat these.
Most cats cannot tolerate frozen or cold food. The easiest way to defrost or warm up raw meaty bones is to place it in a ziploc bag and let it sit in a bowl of tepid/warm water for 10 minutes. Do not make the water so hot that it actually "cooks" the outside of the meat! Cooking destroys almost all the nutrients found in a raw diet which can lead to deficiencies and other health problems. NEVER put a raw meaty bone into the microwave to defrost it. Microwaves cook from the inside out and will cook the bone while the rest of the meat is still cool to the touch. The cooked bone will then be brittle and can splinter. The easiest method for preparing a cats food is to remove it from the freezer the previous night and let it sit and defrost in the fridge, then warm it up in a bowl of tepid/warm water before feeding.
Ensure a balance is given overtime the ratio for feeding cats is the same as dogs
80% meat, ligaments, fat, green tripe
10% edible bone
10% Organs 3-5% of this should be liver
