Why is my kitten meowing? When will she go into heat? Raw food?

Savannah won't go into heat for the first time until she is at least six months of age. If you don't plan on breeding her, I recommend having her spayed before then. Cats in heat are very annoying. No, I do not recommend feeding her raw chicken; in fact, I never recommend a raw diet. You can occasionally give her some boiled white meat chicken (no bones) as a treat. Be sure to be feeding her a kitten formulated food so she can get all the nutrients she needs to be healthy. She could keep meowing because she's hungry, and it may be the grain free food isn't satisfying her. I never recommend feeding grain free unless there is a proven allergy to grains, which is actually very rare. You can try feeding her a high quality kitten food such as Royal Canin, Hill's Science diet, Purina ProPlan, and Iams. I hope this helps!
