Sootyca - lol typical fussy felines!
I think that's one of the things I'm thinking about though. With Moomin it took an absolute age and huge cost to finally get her food sorted. As soon as we started trying different foods, she got very fussy, and would love something then go off it after a few days after switching, and we ended up with her only eating the v expensive wet. This led to dental issues etc, as she would never ever touch dry.
I'm going to chat to our vet when we take him in for his booking in appointment and get their advice on what's going to be best. He's more than happy with the dry at the moment, so for the meantime I'm sticking to that, to help him settle in.
