I was doing some research and I came across this regarding pork used in cat foods. I thought I should share it:
Pork meal is the dry rendered (cooked down) product from a combination of clean flesh and skin (with or without accompanying bone), derived from the parts of whole carcasses of pigs or a combination thereof -- exclusive of head, feet or entrails.
In general, pork is an approved ingredient but there are palatability issues with pork as compared to other meats. It is difficult to make a highly palatable pet food using pork without adding flavor enhancers. Another problem is that there is an inadequate supply of pork meal that is free from by-products.
One word of caution: You should know that problems could arise when cured pork is fed regularly (e.g. bacon). It is high in salt, sugar and sodium nitrite (which has been linked to stomach cancer). All of these substances in high concentrations are unhealthy, and dogs are particularly sensitive to nitrites, which can cause severe reactions in susceptible dogs.
. . . Eagle Pack also used pork in some of their cat food falvours. But not in all of them . . .
