Oh good! Kittens are usually game to eat anything while they are young, so please offer your kitten a variety of canned foods in various textures, flavors, and brands, too. You just never know when Nulo will change its formulation and your kitty will know the difference and refuse to eat anything else!
The other thing about raw, make sure you rotate various types of proteins, too. So many people make the mistake thinking feeding their pet only raw chicken or turkey exclusively for a long time is perfectly fine, not realizing they need to have a more rounded diet from other proteins. I guess it's like you yourself only eating veggies and fruits, and then suddenly you find out you're deficient in B12 vitamin and feel ill?
Anyway, I usually mix up my proteins week to week since I buy commercial raw. I know Primal has several other proteins available, so it could be well worth a try, or perhaps using other commercial brands, or giving your kitty the occasional chicken wing for dental care. Some pet stores will even offer free samples or have a good return policy if it doesn't work out. If your pet store is like mine, they are a wonderful source of knowledgeable people who can definitely give you good pointers on a lot of things regarding your pet.
Good luck, and let us know how it goes. BTW, what is the name of your kitten?
