I have a few that don't care for treats of any sort. My Misty ONLY likes her dry food, no wet, no baby food, no people food, no kitty treats of any type, nope, uh-huh no way, just dry for that picky girl!
I wasted almost $100 on dozens of different treats before I came to the same conclusion: none of my five cats like moist treats at all!!! Nutro kitten food is tastier. My cats hate the taste of glycerin.
Nowadays, I just buy a little tiny bag of Meow Mix Seafood Medley formula and use it as treats. It lasts a long time.
