Castrated tomcat mounts other cats: what to do?

When a neutered cat mounts other cats, it is not always funny for their people, but sometimes also irritating or embarrassing. But what is behind this unexpected behavior?

Did you bring your cat to the vet and have it neutered? This should all amorous feelings be gone, right? There are a number of reasons why neutered male cats can show such aggressive sexual behavior.

Testosterone makes your hangover wild

Testosterone is the hormone that controls your cat's sexual activity. However, it acts more like a dimmer than an on-off switch. Even if testosterone is no longer produced due to castration, the foundations for sexual behavior are laid in the hangover's brain. Castration weakens the characteristics of these systems very much, but does not completely erase them.

In this respect, your darling shows a completely normal behavior when he mounts other cats. You should also keep in mind that it takes about six to twelve weeks after castration for your hangover's testosterone level to drop accordingly. Sometimes the smell of a furious cat is enough to trigger it.

Mating behavior of cats: foreplay and mating

Mating behavior is a kind of foreplay for cats. Has a cat lady got a cat ...

Climb as learned behavior

With early castrations before the sixth month of life, typical male behavior often does not develop at all. However, if the cat is castrated very late, it has already learned the mostly undesirable gestures of masculinity such as urine marking or climbing on. It is no different with your parlor tiger than with people: it is hard to get rid of habits you have come to love. So it can be that your neutered cat jumps on other cats or pillows and plush toys, simply because it feels good.

Sexual aggression to clarify the ranking

If your velvet-pawed Don Juan performs the mating act on his fellows, this can also serve to clarify the ranking. For the hierarchy it doesn't matter whether the other animal is male or female. This behavior can often be observed when new cats are brought into the house. Even if the four-legged friends have lived together peacefully so far, a sudden need for ranking may arise when the animals reach adulthood; that happens between the second and fourth year of life.

Even if it is difficult, you should let the animals fight their social rank with each other and also recognize the winner as an alpha cat, which means that he gets food and attention before the others. While this may not do justice to the human sense of fairness, it means much less stress for the kitties in the long run, since they arrange themselves among themselves.

Solutions for hungry cats

Before you think about how you can stop your neutered male from climbing, it makes sense to be aware of one thing: cats have no shame. Even though the behavior may be irritating to humans, the animals mostly don't mind. So if there are no bad causes for this "very special friendship", you do not have to be active. However, if you really want your cat to stop climbing other cats, you should rely on positive reinforcement.

Distract him with toys and activities, for example, instead of using the water sprayer. If stress is the cause, try to reduce as many triggering factors as possible by creating routine, respecting the ranking and reducing competition for resources, that is: multiple feeding places, multiple litter boxes, many vertical retreats and varied employment opportunities.

Also pay a lot of attention to your room tiger. If none of this helps, and the other cat also suffers from the aggressive-sexual behavior of the hangover, there is sometimes a chemical solution: With pheromones, you can pretend to the loving hangover that the female is a male. In some cases this is enough to stop the behavior.
