I get the Maine Coon Royal Canin biscuits from PaH, which they have all always enjoyed until just recently, which is most annoying as it's one of the best ones you can buy. Don't know why they have gone off it. I have just tried them on James Wellbeloved kitten which they liked for the first day, now they barely nibble at it. Same with that gourmet pearl, they used to like that too.... They have gone off whiskas supermeat, oh so meaty and organic pouches. They have had natures menu in the past and enjoyed that, maybe it's time to try them on that again! I don't know. I got that Almo Nature from zooplus a few times, but it's very costly and they weren't even very keen on it!
I normally rotate the food they get, tin one meal, pouches the next, dry the next, etc. They seem to have no appetite at all and i'm throwing a lot away.
