What happens to kittens when the father is the son of the mother?

Answer 1

Some may be fine. But there is a high chance that one or more recessive genes may be brought out. Any genetic weakness is possible. I cared for one who had the same father and grandfather. She had 3 kinks in her tail, a mixture of long and short hair and was mentally challenged. She had 4 litter mates. 2 were fine, 2 did not survive long. Naomi babcock says :

aside from genetic abnormalities, sometimes you'll get unique kittens! I had a black cat, she was mated by my tabby. She had a litter of all black (some fuzzy, some short haired) kittens. We kept one, when he got old enough he got his own mother pregnant. She had a litter of black kittens once again, but ONE cat that i swear is a sable point siamese. don't ask how, she never got out. my mom has said kitten to this day.

Answer 2

he will trigger her for ovulation ( the midst of copulating to allow her body to produce young) she will most likely not become pregnant in the first round, but she soon will. nothing will happen. hope this helps, silver123

Answer 3

As siblings have much the same genetic background, kittens reared by siblings will often inherit "bad genes" from both sides of their family. This will generally result in malformed kittens or stillbirths.

This is done deliberately, actually, surprisingly often to "lock in" the characteristics of new breeds. A new breed, note, quite often would be considered an inheritable disability; consider the case of the Cornish Rex, a mutation with extremely short hair, curled-up whiskers, and a raised body temperature. A kitten born with these characteristics was bred deliberately to his own mother as a way of producing an entire litter of kittens that had these suddenly-desirable characteristics.
