it's called ol' Roy because ol' Roy is in it!
I also read somewhere that what they call chicken/beef/whatever by products is not nessasarily that. Some organization went undercover in a cheap pet food processing plant and said that anything under the moon is in it.
A partial list (from memory):
cancerous cows
euthanized dogs and cats picked up from the vets, some with collars and tags still attached.
feathers by the tons
This mess of stuff stinks to high heaven and is crawling with maggots and bugs!
All this is moved around with a bulldozer, then cooked to high temps to kill of whatever, bla bla bla, need I say more.
Now I'm really careful reading ingredients and I also make my own dog food. Luckily they're small Yorkies!
Yes I hi-jacked this thread too!
