Father’s genes determine how friendly a cat is

Cat inheritance of father's genes

The genes that a kitten inherits from his father determines how friendly the kitten becomes1. So, I am told. I set about checking if there was agreement amongst experts on this. The mother’s genes also have an affect on the kitten’s personality but the effect is not as strong. This seems strange. But is this nature’s way of allowing the father to have an influence over his offspring’s personality when he is excluded from raising them?

Dr. John Bradshaw at the University of Southampton, UK, writes that:

“A small number of controlled breeding experiments have been carried out in which the behaviour of the sire has been related to the behaviour of its offspring”…(Fabcats website)

So, he agrees. He also writes in The True Nature of the Cat:

It has now been demonstrated several times that tom cats tend to produce kittens that are as friendly or unfriendly as they are themselves. Mothers must also tend to produce kittens that are as friendly or unfriendly as they are, although they will also influence their kittens’ friendliness directly, through their own behaviour.”

The father’s personality is transmitted to his offspring through his genes. The mother affects her kittens’ personality through the way she raises them and to a lesser extent through her genes. If she is timid her behavior will be copied by the kittens and vice versa i.e. a friendly outgoing mother will probably raise friendly kittens through the teaching/learning process.

Linda P Case writes2

..a paternal effect on behavior has also been reported, and this effect is likely to be entirely inherited, since the male cat plays no part in the raising of his kittens

Of course, there are other influences on personality one of which is litter size and socialisation. Apparently, cats born to large litters of four or more kittens, and which remain together for at least 10-12 weeks, are the most sociable cats, subject, of course to other influences such as father’s genes.

When discussing cat personalities people tend to categorise cats into two groups: bold and timid. This is important in the human to cat relationship because bold cats are more likely to have a better relationship with their human caretaker because they are less stressed, which translates to being more friendly. Timid cats require more work to make a good connection and are probably more defensive and standoffish.

In reference to a study by an animal behavior expert, Sandra McCune, Sarah Hartwell writes that:

..friendliness is all about being less fearful and linked to the production of stress hormones…..McCune found that the friendliest kittens were those from the friendly father..

Conclusion: the title to this post is correct.

  1. Hi Michael. Sometimes I select for type and appearance or because they are descended from Ankara Zoo cats and are therefore of particular interest. The best way is to select for character AND appearance as in the case of Muzaffer and now Kahraman. I have sold some cats to European and Uk breeders.

  2. Hi Marc. Yes they are proper Turkish names. Kadir means “big”. Muzaffer means ” Great Victor’ or similar. I sell to Europe and the Uk. American still can’t understand that what a real Turkish Angora is because they have been assailed by the cat fancy fake Angoras for many years.

  3. I see that with my gentle Giant Muzaffer. His kittens are very trusting and are biddable which is quite an unusual trait in felines. Particularly the biggest kitten, Kadir, mostly follows me around like a puppy, and doesn’t want to miss anything. I only have to call him once and he comes galloping over. The other 2 Sofia and Haydar are pretty much the same but like to check things out on their own, but are also biddable. Their mother Risa is very affectionate and attentive too. Another male Balkar, unrelated, was Ok when young but is now nervous and like to get away from people. His initial upbringing was good but maybe the genes from his father kicked in when he grew up. I have only a vague idea who is father may be because he is feral. Never-the-less he is easy to pick up once I get close to him and it is very easy to pop him a pill or tidbit. His 2 kittens are better behaved than he is. Their mother is a friendly cat at ease with people.

    • I love your cat’s names Harvey. Very nice and interesting. I am going to guess they are related to Turkish names..?

    • Kadir sounds absolutely perfect as a companion cat. He is Turkish Angora I presume. Do you sell to people in Europe and America? I don’t know how you operate.

      I guess you select male cats for their character.

  4. A very interesting and useful article Michael. This will help people select the right male for kittens & cats that are likely to behave well at cat shows and be friendly in general.

    • Nice point. If selecting a kitten under any circumstances and you can see and interact with the father, check out the father first. That is probably what one should do.

      I think the bias towards male genes for personality is a compensation for the role the mother plays in raising the kittens and affecting their personality that way. But no one has said that as far as I am aware.
