Just tried the Aunt Jeni's raw turkey yesterday on my boy, and again this morning (his second breakfast) and he REALLY likes it.  I have a local distributor so it's convenient, too.  I'm alternating now between Felines Pride and Aunt Jeni's.  Also bought the rabbit and chicken flavors and will try those next.  No side effects, and he licked the plate clean, and I mean clean.  I picked it up and put it on the counter, and caught DH trying to stick it back into the cabinet thinking it wasn't used!

For any other Canadian members, the equivalent product in Canada is called Home Made 4 Life - http://www.pets4life.com/index.php

We've had our two male Bengals on it (as part of their diet) for several months.  However, they won't take it totally raw, so we have to just "kiss it" in the microwave at a reduced power level.  Kind of defeats the purpose doesn't it 
Our two love the Wild Salmon and will take some Rabbit.  They absolutely would not touch the Chicken, Turkey or Duck, and we had some puking problems with the Beef.
We're currently at the beginning of trying the Feline Future Instinct TC.  Not sure how that's going to go!
