Well, I don't know if they'd go to the trouble to single out the tumor, but "animal byproducts" is everything that's left when the good stuff's been taken. Including the yucky bits.

Not that there's anything inherently wrong with that, really. Some of it is undoubtedly of good use.

I simply reject any pet food that lists unidentified 'animals' in it's ingredients because this is codeword for the less than appetizing product of both horse slaughter, and animal disposal (including euthanized pets) that end up at rendering plants.

If the label ingredients say "Beef" or "Chicken" or "Lamb", or "Beef byproducts" that's what it is. If it says "Animal"... well...

That's one reason why I avoid Tender Vittles and other low-end foodstuffs, although the folks at the local dog boutique say the high-end stuff like Science Diet, Iams Nutro, etc. are just as bad-- of course, they say this while promoting their own, much more expensive dog foods.

I've heard great stuff about a food called Avo Derm, so I might give it a try next time.
