Hello, so my cat has been on merrick purrfect bistro duck pate for a while now, it's his fave food and he won't eat others really, and only duck, he isn't fond of other flavours really. But recently, it has been out of stores for a bit and it came back but he doesn't seem to want it today, it does smell stronger and looks darker as well, I'm unsure if maybe they changed the formula but the ingredients are the same and not expired either. Are there any other grain free, preferably meal free, and pate wet cat foods out there that have duck? I am in Canada, and I don't see too many options for cans that are healthy. Thanks in advance!
