Cats are animals that run on pure instinct. In your cats life, one of the biggest drives they will ever have is their need to make kittens. When breeding, the season comes along, and your sibling boy and girl kittens are both not yet neutered, theyre bound to have sex with each other and eventually have kittens together.
When very closely related cats (for example brother and sister, mother or son, or even half-siblings) mate, the risk of genetic defects increases: inbred cats are more likely to have immune deficiencies, congenital abnormalities, and have inherited diseases. For animals, including cats, how effective their immune system is dependent on their genetic diversity.
Sometimes, even kittens who have the same parents cave inherited random gene combinations unless, of course, if they were identical twins. If you already have an inbred kitten, it is imperative that you sterilize them as early as possible so you completely eliminate genetic problems from entering the gene pool. Most breeders, especially the less reputable ones, resort to inbreeding their cats so the perceived quality most desirable from the specific breed comes through significantly.
There are many things that can influence how early or how late your cat will become sexually mature such as their breed and their environment. If such thing happened accidentally, there is not much need to be worried unless if the cats had signs of genetic issues.
What happens if a brother and sister cat mate?
What Happens If Cats from The Same Litter Mate? If cats from the same litter do mate, there’s every chance that their kittens will be born healthy with no obvious genetic issues. With luck, the litter produced will have all the desired physical and personality traits without any major defects.
Can a cat get pregnant from her brother?
Cats can become pregnant on their very first estrous cycle, increasing the chance that an accidental breeding may occur. Cats are indiscriminate, so a brother cat may breed with its sister, a father may breed with his daughter, and a son may breed with his mother.
Can cats have inbred babies?
It is perfectly acceptable to breed related cat and register their offspring. Inbreeding is the breeding of closely related cats, such as father to daughter or mother to son. … Inbreeding has a tendency to set undesirable features as well as desirable features and should only be done by an experienced breeder.
Is it bad for cats to be inbred?
As recessive genes appear, they can be eliminated by selective breeding. However, there are additional problems with inbreeding cats. … The Cat Fanciers Association of America notes that inbreeding may lead to immune deficiencies, more congenital abnormalities and cats that don’t grow to their potential.
Inbreeding has a tendency to set undesirable features as well as desirable features and should only be done by an experienced breeder. Inbreeding could lead to smaller litter sizes, immune deficiencies, increased incidences of congenital abnormalities or cats that fail to grow to a normal, full size.
Cats bred with certain physical characteristics, such as flat faces and small legs, are at increased risk of getting cancer, kidney disease or joint problems . Dogs and cats don’t grow up with social restraints that discourage copulation between siblings , so when they reach puberty, littermates can and do spontaneously mate .
“Like dogs, cats display social flexibility in regard to their attachments with humans ,” said animal scientist Kristyn Vitale of Oregon State University.
about 7-8 weeks ago I took my male cat to get fixed, he was doing the usual, sparying and stinking the house, so I took him right away before be damaged the house and before he got his sister pregnant. About 3 maybe 4 weeks later I saw my female cat acting weird, I looked at her stomach and it looked like she was pregnant, MY MALE CAT GOT HER PREGNANT, HER BROTHER! she looked the same when her sister was pregnant about 3 months ago, but she’s not my cat that’s my aunts cat. Anyway, my cat‘s nipples her getting bigger and pink, and they previously didn’t look like that! she’s always been extremly loving but now she’s more! I touched her tummy (which is weird because she never let me!) and her stomach felt kind of hard. I waited a couple more weeks and now I can feel her babies move, she was always a small cat, she’s a little over a year old and she looked like she’s 5 months old before she got pregnant! I noticed that she is getting a bit bigger, not fat, just her tummy is bigger.
It means more unwanted kittens in an already crowded shelter world (if you are correct)
Yes, cats, if not fixed, will get their relatives pregnant. The female and babies should be in another room, door shut, away from small kids, a lot of noises, etc..preferably in a large box when she will allow you to put them there.Get RID of your male cat?
As far as the sister carrying her brothers babies…it is not ideal but it happens all the time in the wild…I doubt you will have deformities…but again, please have them nuetered and spayed before these troubles come along…it saves A LOT of heartache Make sure you provide her with a safe, warm, dimly lit nesting box or area and keep the normal traffic of your home away from her until she is ready to bring the kittens out. This is after seven litters last year and a lot of supervision, though.On the other hand, I’ve heard of daddy cats grooming newborns in the box with mama.
