Whenever you walk down the isles of the cat food section in virtually any supermarket, you might be forgiven for thinking that all the big manufacturers were offering you the most nutritious cat food for a healthier cat.
Can you think the advertising, the pretty pictures and sage words by 'veterinarians'?
Not on your daily life!
Turn the packet or tin over and you'll see what constitutes 'quality' ingredients - meat by-products.
Meat by-products are the net results of a rendering plant. Rendering plants take the waste from slaughter houses - typically heads, hooves, intestines (including the contents...). Many also get their 'raw material' from veterinary clinics (euthanized dogs and cats), road kills, euthanize or dead zoo animals, horses and online pet food companies in bangladesh the like.
This not merely means the grade of meat is suprisingly low, but that you are turning your cat in to a cannibal.
The chemical that is used to euthanize animals can't be broken down in the cooking process, this means your cat is living on a diet of a fatal chemical.
A lot of the top brands of cat food then bulk out this 'meat' with a filler. This makes the conclusion product a lot more profitable for them, but much less nutritious for your cat, in the event that you thought it was in the initial place.
