Opposite Sexes of Neutered Cats Get Along Better
I am sure a lot of people prefer to adopt a female cat over a male cat and vice versa. There is a possible reason why a person should adopt a male or female cat if there are cats already present in the home and a new cat is to be introduced. It is said that opposites attract.

Therefore, in a multi-cat household introducing a neutered male cat to a group of spayed females has a greater chance of successful integration than if a spayed female were introduced.
A male cat is more likely to get along with a small female than with a large male cat. I have been unable to confirm this from a study or research. However, common sense says that opposites are more likely to attract because to a male cat a female is less threatening. Even though the neutered male loses a lot of his territorial motivation and his sex drive, some of these behavioural traits remain. The potential territorial problems are lessened between male and female cats compared to male and male cats.
In the wild, the male wild cat of the species normally has a larger territory than the female and it can include the female’s territory. This arrangement is harmonious. There is no overlap between male territories. This supports the idea that opposites attract for neutered domestic cats in multi-cat environments. Or to put it more accurately there is less of a chance of repulsion.
Has anyone had any experience of this?
