I absolutely agree with what you say Cara, and that is why my cats still eat commercial food. I don't dispute that the PFMs supply all the required nutrients, it is the chemical additives and preservatives that are the real baddies. Cats are far more difficult to deal with, than dogs, as they are more fussy, having said that I would not feed my cats exclusively on dried food as no matter what the pet food manufacturers/vets say, dried biscuits only, can not do any animal any good over the long term. Mine have
some biscuits, mainly wet food and some tinned fish or cooked chicken, also mice and birds
Dogs, on the other hand, and I have done extensive reading on the subject, are not difficult to feed. What you have to keep in mind is what they would eat if they were non-domesticated. Dogs are scavengers and so their digestive system is designed to cope with a variety of foods, although they are predominantly meat eaters and thus should be treated so. Their stomach acid is capable of digesting bone and so it follows that many of the bugs that would lay us low, such as salmonella, do not have such an effect on dogs. One of the ways of feeding is "whole prey". For instance if a dog caught a rabbit, it would eat the lot - usually stomach contents first - which is where vegetable matter comes in to the equation; followed by meat, bones and fur. Thus, when raw feeding, one would try to achieve a balance of meat, bone and offal, with a little vegetable matter thrown in. Interestingly enough, raw fed dogs do not suffer as much with anal gland trouble, for when they poo, they give the anal glands a workout, for passing digested bone is harder than pooping out the waste from dried food. Nice subject
On the bright side, raw fed poop smells less and there is not as much of it
You could argue that chicken wings from the supermarket have little calcium content as opposed to free range chicken which we know have denser bones; anti-biotics and growth hormones, play a part. It is a complex and controversial subject....
