Oh yeah that’s true. Actually now that I think about it, I had a female cat that got pregnant once and all her babies were black. But she has some white spots that you can only see up close. Her babies were like that too. There is a cat in the neighborhood always hanging around that is black so I assumed that was the dad. She got pregnant a second time and they were all black again. But the third time she got pregnant, she had kittens that were black and two different kittens that were white with gray paws. Like a Siamese. I assumed it was possible because she had some white spots. But it came out of nowhere and still didn’t really make sense. Eventually I saw another cat that was white. But I assumed that it was just one cat that knocked her up. Your explanation makes more sense. She was a little slut 😂
