Even after being neutered, the male may become stimulated enough to try to mount a nearby female cat in heat due to her scent. A neutered male can even display mounting behavior toward a spayed female.
The best solution for this is neutering or spaying. One other funny solution is to regular spray some water when the male does this to the kittens, and then he will be too afraid to do it. Spraying water is not enough to keep the tomcat away.
Cat humping is a natural thing, and it occurs for many reasons, the most important of which is hormones. Intact male cats will hump female cats as part of the sex act. They may also hump other male cats in the home, which is viewed by most experts as dominance behavior.
Male cats will often mark their surroundings with urine and pheromones to attract females and ward off other males. Attempting to mate is an obvious sign that your cat is at the mercy of their hormones. Mating behavior may appear as a cat fight, as the male will pounce on, bite, and growl at the female.
They show affection by rubbing their heads against each other and along the sides of their bodies. Sometimes cats may even hook their tails and rub them together. Cats typically do not rub against each other's backs.
It's an act of dominance. This is actually how cats mate. The male bites her on the back of the neck to hold her in place, and she yowls because the male organ is spiked and hurts like heck when he pulls it out.
The action you describe mimics the breeding posture and behavior. This can be a pleasure thing or a dominance thing. Some cats will do this because they like to… and will do it to other cats, stuffed animals, dogs, etc. If it doesn't bother your other cat – then maybe it is not worth worrying about.
It's normal and natural for a male cat to enjoy the sexual pleasure he may experience from this activity. Some cats that hump are insecure or need extra affection. Trauma or surgery can cause humping. If your cat is bored, frustrated, or feeling too confined.
If you also have a male cat, it's a good idea to keep them separate. If possible, see if you can move the male out of the house until the heat cycle ends. If that doesn't work, put them in separate rooms so they can't interact.
You really only have two options: get him fixed, or separate the two cats. So give your young female a completely separate living space (or give it away), or get the male fixed. Getting the male fixed is by far the best solution, as it ensures that he won't ever make unexpected kittens for you or anyone else.
Cats in Heat May Need Some Extra Playtime
For cats, the urge to mate is instinctual. So is the urge to hunt. Try to keep your cat occupied with exciting toys that stir her hunting instincts. It may take her mind off her other drives.
Male cats don't have heats. However, if unneutered, they reach sexual maturity around the same age as their female counterparts — as early as four months, but usually closer to six months of age.
Castration reduces roaming in approximately 90% of cases. Although neutering greatly reduces sexual interest, some experienced males may continue to be attracted to, and mate with females.
A female cat doesn't go int into heat to get laid, but in order to get pregnant. So yes, if the neutered male is interested (some are, some are not), he will absolutely and successfully mate with her -but since he is neutered, she will not become pregnant, and thus nothing will change.
If your cats' bodies are relaxed or their ears are pointed forward, they're likely just playing. If your cats flatten their ears, hold their ears back, or puff up their fur or tails, this is a sign that they're fighting, not playing.
This is most likely when something has recently changed in the cat's environment like the addition of a new family member, a move, or even a neighborhood cat that can be seen from a window. Boredom is another cause of humping in cats. However, cats also use mounting behavior as a way to reinforce social ranking.
Some cats will act dominantly in one room with one cat and suddenly switch roles in another room with another cat. Mannerisms from the dominant cat, such as excessive licking, standing on, or sitting on the other cat may be displayed, and swatting and even biting may occur.
As odd as it may seem, male cats spring on a receptive female and bite her in the scruff, pinning her down as they intromit for a few seconds of orgasmic pleasure.
Males go into heat once they reach sexual maturity. Heat in the male cat is an incessant condition. This means that he is ready to mate whenever the opportunity arises.
Spraying often starts around six months of age as cats reach sexual maturity.
Locating a Mate
Female cats in heat (in the estrus cycle) exude a powerful sex pheromone that can be sniffed or "scented" by a male even at a distance of a mile away.
Cats take one to two minutes to mate. Thus they can repeat the process multiple times within a short period. A queen may mate with different tomcats during the heat cycle to make it possible that a litter of kittens may have different fathers.
Male cats scream when they are in heat. Tomcats yowl a lot at night to make themselves easier to hear. Like their female counterparts, they announce they are now ready to become a father. Male cats are also more agitated toward other cats during this period.
The typical cat pregnancy will last between 63 to 65 days, or about nine weeks. However, there are exceptions to the rule. Just like humans, cats can sometimes give birth a little early or a little late.
