Are Exotic Meats Nutritious or a Novelty?

Answers: Are Exotic Meats Nutritious or a Novelty?

I understand that cats need to eat a variety of different meats when being fed a raw diet. Mine currently eat chicken, turkey, rabbit and some pork. I have noticed that a few places are offering what I think of as very unusual meats, such as ostrich, emu, kangaroo, yak, llama, elk and even muskrat. I know cats in the wild will eat pretty much anything that is available that they can catch, so are these more exotic meats okay to add to their diet? Or are they more of a novelty that appeals to humans?
Great question. A variety of meats is crucial to a raw diet. The simplest way to think of it is that each animal consumed by your cat has a different nutrient profile, dependent on what that animal has consumed in its lifetime. So, feeding a variety of meats from a variety of sources ensures a full range of nutrients for your raw fed cat.
We also have to think whether the meat source is exotic to us, or to our cat. Pork would be a food source very unlikely to be eaten by feral cats, so, do we call it an exotic meat? Our New Zealand possums, which might be considered an exotic meat, are packed full of essential fatty acids as they consume all our beautiful native bush and native berries.¹ Feral or wild cats naturally consume what crosses their path, such as insects, frogs, birds, rodents and rabbits and regional differences are common in the dietary habits of feral cat populations.² Cats will also feast on larger animals if bigger hunters have killed them first. They have a preference for very fresh meats, so will only eat fresh kill. What this means is that cats can and will eat most exotic meats. Whether they should or not is actually harder to answer.
Take beef for example. Cats wouldn't naturally hunt cattle, so for a cat, it is an exotic food. In my professional experience, I have found that cats fed daily on beef have a higher incidence of asthma and allergies. Beef is a meat that is higher in histidine than other meats, and histidine can cause inflammation.³ Ingesting higher levels of histidine, over the long term, can result in a zinc or copper deficiency. Zinc is an important co-factor for digestive enzymes and for the production of hydrochloric acid, so it is very important in cats with IBD. Copper helps tyrosine work as a pigment factor in fur and a loss of coat color is one of the early signs of a copper deficiency. In my practice, we often see cats fed only beef developing a change in coat color from black to rusty brown.
I find that cats fed beef occasionally, up to three times a week, seem to cope with no problems, though. In the past, cats were often brought up on gravy beef, which is a cheap cut from the butcher. But, we have to remember that these cats would also have been hunters working for their keep, keeping the rat and mouse population low and feasting on insects and birds. In my own practice, I would say that feeding exotic meats to add variety to the diet is a really good idea. Here in New Zealand we can access wallaby, ostrich, alpaca, and possum to name a few exotics. But, we don't over feed any one source of meat. Up to three meals a week would be the maximum for one meat source if it doesn't really seem bio-appropriate.
