What color kittens...?

[olliecatsmum]

My female cat, Marcy, is all white with short hair, green eyes and full tail. Her mate is a purebred American Bobtail, but she is a mix. He is mostly white with two or three blue/grey patches. Will the litter be mostly white or can they produce color?

It depends in much, on her parents.  I presume one was white, and one colored, as you say she was a mix?

Daddys parents carried both white?

Half should be white, the other half a combo, where many / all has much white fields  (ie the white spot gene from dear daddy)

OK, I was going to explain about the W gene, but one site I found said that cats with the W gene (dominant white) always have blue or orange eyes; cats with green or yellow eyes are white because of the S gene (white spotting) :dk:.

Also, she has a genetic color being masked by the white---do you remember if she had any small color spots as a kitten?

But I'll say a little about the W gene just in case. If she had the dominant white gene, that would mean she either has W/W or W/w (a cat must have the W gene to be visibly white, unless it's the S gene). If she has W/W, this would mean she could only pass on the W gene so all of her kittens would be white. If she has W/w she could pass on either one so about half the kittens wouldn't be white.

The S gene, which is what the father cat has, is the white spotting gene. A cat can be all white with this gene---basically they're all one big white spot . So maybe the mother cat has this gene too. Most high-white S gene cats have S/S, so they can only pass on S so all kittens will be white spotted. The exact amount will vary but they'll be mostly white. If the parent cats happen to have S/s (they would probably have less white if so), then some (about 1/4, I think) of the kittens would have a chance to not have white spotting.

But most likely: all the kittens will be mostly white with spots of color. Unless the thing about eye color is wrong, and then either 50% or 100% of the kittens will be solid white. It all depends on which kind of white the mother cat has.

Marcy was adopted as an older kitten so I know nothing of her lineage, but I do know that she had a solid white brother who also has yellowish color eyes. They were the only two in the litter I believe

Are you a breeder? Do you own dad too?

 

[olliecatsmum]

No, not a breeder. I don't own the father my friend does

How old is she? Do you plan to spay after this litter?
