As a kid, we had a cat that was given a taste of cooked liver. Effect was astonishing. Went on a hunger strike, wouldn’t eat anything else. We learned it would eat raw liver. Liver was cheap back then. Guess who had the job of cutting up the raw liver to feed the cat?
Good result was, we never had liver for supper again. SWMBO likes liver and onions. She can eat it in restaurants (remember them?) but not at home. I prefer not to eat another creature’s poison filter. Or smell it.
All cats I’ve had since have had canned and dry free feeding. I might go grain free, as I have for the last two we had. Someday, I expect we will serve cats again.
