Cats breeding with siblings : All you need to know

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.

Some animal breeders purposefully pair brothers and sisters to maintain bloodlines and develop desired pedigree-associated characteristics.

Conversely, inbreeding can also lead to birth defects, an increased likelihood of genetic diseases, and chronic health problems.

Call to Breed in Dogs and Cats

At the point when a female goes into heat (otherwise called the estrus cycle), guys basically follow their intuition to pass on their qualities with no worry for the hereditary repercussions.

Littermates living in a similar home normally react when everything looks good. The estrus cycle differs in pooches and felines.

The time of creature adolescence fluctuates. It can sneak up on you, bringing about a spontaneous pregnancy and the stun of an extra five to 10 pups or little cats in your consideration.

As a rule, canines and felines enter adolescence at around a half year old enough, however it can occur for some at four months old. Pooches go into heat on normal two times every year; however some may cycle pretty much as often as possible.

Felines, then again, cycle into heat about like clockwork during a reproducing season that by and large happens among January and October.

A feline in warmth may abruptly become vocal or begin showing extreme fondness. An indoor feline who needs to get outside can likewise demonstrate a warmth cycle, while the estrus stance of butt noticeable all around with tail inclined aside might be the most telling sign.

Female pooches may pee exorbitantly, lick their private parts and appear tenacious and disturbed. Grisly release and a swollen vulva likewise happen with a pooch in heat.

Indications of warmth can likewise be indications of an issue, for example, a urinary tract disease, so observe your vet at whatever point you feel unsure of the reason for a specific conduct.


The normal canine pregnancy keeps going 58 to 68 days and a catlike development period takes 64 to 67 days. Factually, most pooches could securely create two litters for every year except a feline could practically conceive an offspring multiple times.

This would not, in any case, be useful for your pet’s wellbeing or life span, and could bring about overpopulation and the passing of undesirable creatures.

Pregnancy can without much of a stretch become an issue when you embrace sibling/sister littermates or keep litters of little dogs and cats past the age of 4 months.

The beginning of the principal heat cycle, when a female can get pregnant, follows a similar time span as adolescence (4 to a half year) for felines and little mutts, however it might be postponed until 18 to two years in bigger types of pooches.

Preventing Pregnancy

The only guaranteed way to prevent unplanned pregnancies is to spay or neuter your pets. Animals can get creative when there is a female in heat.

Keeping males away when pets live in the same household may prove difficult or even impossible.

Consider shaving your pet spayed or neutered to avoid contributing to the huge problem of pet overpopulation.

According to Quora user : Answer 1

My youngest cat Cupcake has a bro-dad. That’s what my daughter calls him. Her brother is also her father. Her mother obviously mated with her own son. Incest isn’t a taboo in the feline world.

I had no idea about Cupcake’s paternity until after we had brought her into our home and bonded with her. I honestly don’t know if it would have made a difference or not had I known prior. I think I still would have taken her, but I would have been cautious about her health.

She has no deformities of any kind and no behavioral problems that are apparent. The only issue is her dental health. I brush all my cats’ teeth regularly, but her teeth are decayed even so. At 4, most of her back teeth have been pulled. My 14 year old Phoebe died with all of her teeth intact, and my nearly 15 year old Sam also has healthy teeth. I’m not sure if her tooth issues are due to inbreeding, but it’s the only difference between the cats.

I realize that I went into a little more than the question was asking, but I figured I’d let people know my experience. No matter what, she’s just Cupcake and she’s loved.

Answer 2 :

If not neutered or spayed then yes it can and does happen, especially if they have limited access to other cats, they will also mate with parents or children. For cats mating is down to a purely biological drive, they dont make the same distinctions or have attraction or relationships.. most animals are exactly the same and for many it is far more common where oportunities to mate outside family are limited. It can and does cause birth defects and health problems or for kittens to die in utero as well, which is also bad for Mummy cat. It is another reason why it is so important that people always spay and neuter their cats as early as possible.

Answer 3 :

Yes. Nature impels, and if neither sibling has been spayed or neutered, mating may occur between feline (or canine) siblings.

Probably another reason that feral cats, or cats in the wild, may go some distance from their original home to find and take over a territory: they are then less likely to interbreed over time. Nature has many ways of insuring the health of species.

Answer 4 :

There is an old joke, i try to translate:

An old Lady calls for the vet because her cat seems to be ill.
The vet tells her the diagnosis: “The cat is not ill, but pregnant.”
But the old Lady insists: “That cat never had contact to any tomcat.”
At that moment a big tomcat enters the room.
“What about him?” asks the vet.
Answer the old lady: “But he is her BROTHER!!”

Answer 5 :

Yes, it can happen. The bloodline is tainted then and deformities, abnormal behaviours etc. can be passed on generation to generation.
