Will a grey kitten turn black?

Black kitten.
It is doubtful that a smokey grey kitten’s fur will turn black once they grow up. This is because their fur is already a diluted shade of black. However, some kittens are born in a very dark shade of grey. Their fur is so dark that you can see the black in it, so it’s common for those kittens to end up turning black.
If your kitten is a paler grey then they will most likely stay that shade, as most cats stay pretty close in color to how they were born.
What color kittens will a black cat have?
Each cat carries a single gene on the X chromosome for its coat color. There are 2 color variants that the gene could be, which are orange or black. Each color can be diluted, so a black cat can have kittens that range from dark black to pale grey.
That being said, male cats only have one X chromosome while females have 2. If a black male cat mates with an orange female cat then there is a chance that the cat could have some white or paler tones, especially on its underside.
Color schemes are also different between male and female cats. A male cat will have black fur with various markings and tones. Things are a little more complicated for females because they can have both black and orange X chromosomes, creating an unpredictable mixture.
