If you’ve noticed your male cat being more than eager to get outside lately, yowling at the door, and being quite the nuisance, it could be because he smells a female cat in heat.

Your male can smell a female cat in heat from almost a mile away due to the pheromones the female puts off during her cycle. We’ve got you covered if you’re trying to keep your male cat from getting outside to find the female in heat. We’ll talk about everything from how to tell when a cat is in heat to how to keep your cat safe during this time, so join us.

How to Tell Your Feline Is in Heat

If you have a female cat, you’ll need to know the signs that the cat is going into heat or is already there. The most noticeable sign is your female becoming overly affectionate, especially if the cat is usually a loner who doesn’t want much attention. If your cat suddenly wants all of your attention, she might be in heat. This isn’t the only sign to look for, however.

The other signs include the following:

  • Rubbing her back and rolling around on the floor
  • Loud vocalizing
  • Arching her back and placing her hindquarters up
  • Urine marking
  • Discomfort and frustration

How Far Can Your Male Sense a Female in Heat?

As previously stated, a male cat can sense a female in heat about a mile away. While you may think it’s safe to keep your male cat in the yard so that he can’t track down the female, it’s not. If your male can’t get the female, she’ll sniff out the territorial markings left by your cat and come to him instead.

Trying to get out and get to a female cat could be very dangerous for your male, especially if you live in a high-traffic area. The best way to stop your male cat from escaping to find the female he can smell in heat is to neuter him. This will greatly increase your cat’s quality of life and safety.

The Benefits of Neutering Your Male Cat

Many pet owners don’t realize the benefits of neutering their male cats. They feel that it’s only necessary to spay a female cat, as she’s the one who can get pregnant and produce kittens. However, there are quite a few benefits to neutering your male cat.

  • Eliminates or reduces the chances of your male marking and spraying his territory
  • Reduces the chance of your cat becoming injured or lost when he escapes looking for a female
  • Reduces the chances of your cat getting into fights
  • Reduces the population of unwanted kittens
  • Can decrease aggressive behavior
  • Helps your cat to live a longer, healthier life
  • Reduces the risk of testicular cancer
  • Reduces the risk of prostate issues

These are only a few benefits of neutering your male cat. There’s also the benefit of doing your part to help the strays forced into shelters and often put to sleep because of overcrowding.

Tips for Keeping Your Male Cat Safe

If your male cat gets out and can find the female he smells in heat, you have to worry that he will become lost or worse before he can make it safely home.

The best thing to do is keep your male inside, whether neutered or not, so he can’t roam. Neutering a cat cuts down on the need to roam. It helps to know that a female cat goes into heat every 14 to 21 days and stays in heat for around 7 days but can be in heat anywhere from 2 to 19 days. If the female mates, the heat will pass between 24 and 48 hours. It’s best to get your female or male cats fixed as soon as they are old enough.

Final Thoughts

A male cat can smell a female cat in heat for around one mile. That also means a male will try to escape and head out to find the female. This could lead to your cat being in danger, as he could get struck by a car, hurt in some way, or lost and be unable to find his way home.

While it’s best to have your male cat neutered when he’s old enough, keeping him inside is still a good idea if there’s a female cat in heat in the area. Spaying and neutering benefits cats’ health, reduces the community’s population of stray cats and reduces the chances that your cat will escape your home.
