Poultry and Pea Free Kitten Food

I'm in search of a Poultry and Pea free kitten food but seem to be having a lot of trouble finding a decent brand that does not contain extra fillers that is specifically for kittens. I have come across ones that are tuna but am unsure if that would be OK to only feed them this. At this point I'm OK with kibble or wet food, just trying to find something. I have 3 1/2 month old male and female kittens. Thank you!
