Fingers crossed for you Khadsell. It's a complete crapshoot trying to figure out what one kitty will eat, let alone three! My girl only does pates, and she's eaten these brands for at least a month: Dave's 95% line, Merrick's Purrfect Bistro, Wellness CORE, and Holistic Select. She used to get Instinct dry (rabbit), and I like Instinct in terms of quality, but their pates are not very smooth, and she didn't like them. She just recently starting eating Wellness CORE again, and regular Wellness. Unfortunately, she has advanced CKD, and Wellness isn't the best brand for CKD kitties (pretty high in phosphorus, and it has cranberries, not good for kidney kitties).
Stella&Toby, if you're interested, Instinct - and I believe Stella and Chewy's as well - also does frozen raw (not dehydrated). The Instinct raw bites are tiny, each one not much larger than a piece of kibble, so it's a nice way to try to introduce raw if you're interested.
