My cat would never eat the cuts in "gravy and cuts" or anything that was in "gravy". Maybe that's because it was from a grave.
At the end of his 18 year life, he liked chicken thighs the best. I'd broil them and debone and skin them and he loved them.
My former cat was raised on horse meat with cereal and vitamins mixed in, until I couldn't buy horse meat any more...I think they passed a law against selling it here in California.
Usually I avoided that stuff but occasionally accidentally picked up a can of it, always tried to buy a variety of flavors, knew a few to avoid.
I was thinking of dark meat chicken, too. I like the broiling idea, would be good enough for me to eat that way, love thighs, but mine seems to need the extra fluids for awhile although I've seen her drinking water again.
Just went through the list, all I've bought for years and years were Whiskas and Friskies, always supplemented by dry if they would eat it, don't see them on there, never tried Iams canned and always shied away from store brands. Mine used to love Mealtime, and I haven't been able to find it lately.
This is a mega serious matter, could shake up the entire pet food industry, probably will be class action lawsuits, not pleasant to contemplate the magnitude of it.
I remember my dad picking up horsemeat when I was young as a supplement/treat for my grandmother's dog. It isn't in the stores now, so must be illegal, never liked the idea of eating horses anyway. I remember somebody got busted for selling it as ground beef when I was a kid, and I remember the nasty taste of whatever it was we got from that place. We quit going there. That was in Illinois, but I remember seeing packages of it in the meat section when I was a kid in Iowa.
Until this gets sorted out, there will probably be a shortage of brands not on the list so we'd better be prepared for who knows what? Somebody mentioned the health food store. I did pick up their dry cat food which my cats seemed to like, but it's an extra stop and added expense to go there too often.
