While male cats don’t go into heat per se, their behavior does tend to change when they are around female cats in heat.

If you have a male and female cat in the same house, you’ll want to have this information.

What Causes Male Cats to go into Heat?

Male cats become instantly triggered by the smell of the secretions that come from a female cat’s vagina and urine when they are in heat. The cat’s incredible sense of smell immediately picks up on this, which can lead to all sorts of acting out behavior.

When Do Male Cats Start Going into Heat?

A male cat starts reacting to female cats in heat once it has reached full maturity. This usually occurs within a period of six months, though it can vary a bit. Once a male cat has reached puberty, it is capable of reproducing with females.

Signs of Male Cats in Heat

While male cats don’t go into heat the same way that females do, they do display a variety of behaviors when one is around. Some of these behaviors can be destructive and even dangerous to both humans and other felines.

1. Vocalizing

It is extremely common for male cats to become much more vocal when they are in the presence of an in-heat female. You will notice a lot of yowling and other noises from the male cat. This is just their way of attracting a mate, but it can be rather irritating.

If you have a male and female cat in the same house, you can expect to hear from both of them quite a bit. This is enough to drive even the most patient cat owner crazy, but it, fortunately, shouldn’t last very long.

2. Urinating

When a male cat is outdoors, it marks its territory by urinating on the spot. One of the main reasons it does this is to let females in heat know that it is a suitable mate.

Some people who have a male and female cat in the same house find that the male cat begins urinating outside of the litter box. This is fairly common when the female is in heat, but it is not behavior that should be tolerated.

3. Aggression

If there is a situation with numerous male cats and a female in heat, aggressive behavior is very common. Male cats often fight with other males as a way of showing the female that they are worthy of mating with.

It is important that you keep an eye out for aggressive behavior if you have more than one male cat and a female at home. Things can get ugly really quick if all of the males are not neutered. This is a natural territorial instinct that cats have, and they can even lash out at their owners.

You should be extra careful about handling any male cats in your home if there are females in heat around. It is pretty easy to get clawed up if you aren’t careful.

4. Scratching

Male cats tend to scratch and use their claws a lot more in general when a female in heat is close by. This can mean more than just getting some scratches on your arms. It could also result in having your furniture, carpeting and other things damaged.

Although the male cat is not in heat, it is acting more aggressively than normal. They are frustrated because they have a strong urge they are not able to satisfy. It is important that you prepare for this if you have female cats in the house too.

Should I Get My Male Cat Neutered?

A male cat that has been neutered will no longer react to a female that is in heat, which can be a good thing for numerous reasons.

Some of the best reasons to think about having your cat neutered include:

  • Aggression control: Male cats can get very aggressive when they are around a female cat in heat. If you have both a male and female under the same room, you should considering having the male neutered. This will serve to eliminate excessive aggression, which can become a real problem.
  • Prevent health problems: Cats that are not neutered can develop serious health problems, some of which are life threatening. They can get infectious diseases that are then passed onto the kittens if breeding takes place. This includes “feline AIDS”, which can be fatal.
  • No more noise: If you are tired of dealing with all the noise your male cat makes when the resident female is in heat, this is a good solution.

If you want to get your male cat neutered, you shouldn’t wait more than six months after they are born. This is when they reach puberty, so you’ll want to keep that in mind. Waiting too long to do this can minimize the benefits.

How to Deal with a Male Cat in Heat

If you have an un-neutered male cat and a female that is in heat, you should consider giving one of them to a family member for a couple of weeks. This can help with keeping the peace in your home, as things can quickly get out of hand in this situation.
