Baby Kittens Meowing

It makes a demand and gets mom s attention. They are from 2 sibling mother cats and they live in my grandmother s yard. Sudden meowing in a usually quiet kitten there is a difference between a kitten meowing from the time he moves into his new home to a usually quiet kitten who suddenly becomes vocal the latter could be due to either sickness some cats can meow more when they re not feeling well or if you have a female cat she could have come into heat.
