How to Tell If Your Siamese Cat is in Heat

Female cats usually go into heat several times a year. They will exhibit certain body language cues during this time. They also make specific vocalizations to let males know they are ready to mate. 

You should know how to tell if your cat is in heat, especially if you’re not planning to breed your cat. You can take appropriate measures to prevent her from becoming pregnant this way. 

In this article, I’ll discuss the signs of a Siamese cat in heat and give some tips on how you can help your feline. Keep reading for more information! 


What Age do Siamese Cats Go Into Heat? 

Siamese cats generally go into heat for the first time between six and ten months old. The heat cycle lasts for about two or three weeks. 

The feline heat cycle consists of four stages: proestrus, estrus, interestrus, and anestrus. During the proestrus, which can last up to two days, your Siamese cat may seem restless or agitated. She will also start calling out for mates. 

During estrus, which lasts around four to six days, the Siamese cat is receptive to mating. 

Your cat’s bizarre behaviors will fade away during the last two phases. Your cat will be back to its normal self in no time. 

Note: A Siamese queen will go into heat again after a couple of weeks if she does not become pregnant after mating. However, if mating is successful, pregnancy will last for approximately 63 days.

How Do I Know If My Cat is Starting Heat?

Your Siamese cat will go into heat several times a year if she is not spayed. She will exhibit certain behaviors that can be a bit of a nuisance during this time. 

1. Siamese cats in heat will often arch their backs and raise their hindquarters in the air. This position makes the cat’s rear end more accessible to potential mates. It also allows the cat to urinate more easily. 

2. Siamese cats have distinctive “yowl,” and this sound becomes even more pronounced during heat. 

My Siamese cat, Robyn, is usually pretty quiet, but she turns into a yowling machine when she’s in heat. 

She may yowl or cry for hours, and her voice will be particularly loud and insistent. 

3. Siamese cats in heat will often roll around on their backs, exposing their bellies. 

4. You may notice that your Siamese cat may hold her tail upright or tread her hind legs as a sign of her readiness to mate. 

She may also hold her tail to the side in a lordosis position. 

5. A Siamese cat in heat is restless. Siamese cats are very active and continue to be active when they are in heat. This can make them difficult to keep track of, and they may seem like they never rest. 

Provide your Siamese cat with plenty of toys and opportunities to play when she’s in heat. This will help burn off some of her energy and hopefully make her more manageable. 

6. Siamese cats in heat can be especially demanding of their owner’s time and attention. She may constantly follow you around the house, rub against you, and purr. She may also try climbing into your lap or sleeping beside you in bed. 

While this can be sweet, it can also be overwhelming sometimes. So, be prepared for your Siamese cat’s extra affection when she’s in heat. 

There are a few things you can do to help manage this behavior: 

  • Create some designated Siamese-free zones in your home where she is not allowed. This will give you some much-needed space when you’re busy with work. 
  • You can try training her with positive reinforcement to only ask for affection when it’s convenient for you. Siamese cats are intelligent and respond well to training, so this is definitely worth a try. 
  • Make sure to give her plenty of attention when she is calm and relaxed. This will help her feel loved and secure. 

7. Siamese cats in heat exhibit excessive grooming. They are prone to this behavior, as they try to remove all the scents from their bodies in an attempt to attract mates.

This behavior may be cute or amusing to some, but it can actually be quite damaging to a Siamese cat’s health. Excessive grooming can lead to bald spots and skin irritation. It can even lead to digestive problems if the cat ingests too much hair. 

You must keep an eye on your Siamese cat’s grooming habits and consult with a veterinarian if you notice any changes. 

8. Your Siamese cat wants to go outside more often. Your indoor Siamese cat will insist on going outside if she’s smelling male cats and is looking for a mate.

9. Siamese cats are prone to marking their territory when they’re in heat. You may notice your cat urinating more frequently or in unusual places. She may also spray urine on vertical surfaces, such as walls or furniture. 

10. Siamese cats in heat often lose their appetite. They may not eat as much as usual or skip meals altogether. This is perfectly normal and nothing to worry about. However, if your cat seems to be losing more weight than usual, take her to the vet to rule out any other medical causes. 

I can always tell when my Robyn is in heat because she starts acting strangely. She will spray urine all over the house. Then, she will run around like crazy, trying to catch anything that moves. She wanders around the house aimlessly and will constantly lick her paws sometimes. 


How Can I Help My Siamese Cat? 

Our furry friends can reproduce at an alarming rate. For example, a Siamese cat in heat can produce up to 10 kittens. It’s tempting to want to keep one or two of the kittens for yourself, but there are already too many cats in the world. 

According to the ASPCA, 920,000 shelter animals are euthanized annually (390,000 dogs and 530,000 cats). The number of dogs and cats euthanized in U.S. shelters has decreased from 2.6 million in 2011. Consider the plight of these homeless and stray cats before you allow your Siamese cat to be bred. 

Siamese cats typically go into heat several times per year. There is potential to produce large numbers of kittens if you allow your cat to breed indiscriminately. 

Spaying or neutering your pet is one of the best things you can do to help reduce pet overpopulation. 

  • Spaying is a surgical procedure in which the ovaries and uterus are removed. Most vets suggest spaying your female Siamese cat before she reaches six months of age. 

Spaying reduce the chances of developing mammary tumors by 90 percent if the surgery is performed while the cat is still young. 

  • Neutering is a simple and non-invasive surgical procedure. It will help to calm your cat’s hormones and reduce its urge to mate. 

Vets recommend neutering your Siamese cat before he reaches six or seven months old. 

Spaying and neutering procedures are safe and will not change your cat’s personality. 

Besides helping control the pet population, spaying and neutering also have health benefits for your cat. 

Siamese cats are particularly prone to pyometra. This is a life-threatening condition that affects the uterus. Spaying your cat before she reaches sexual maturity is the best way to protect her from this and other health problems. 

It’s much better to spay your Siamese cat than to allow her to go through the hassle (and danger) of heat cycles. Many Siamese cat owners opt to have their cats spayed or neutered to avoid constant cycles of disruptive behavior. 

Conclusion 

You can tell if your Siamese cat is in heat by its behavior. Your Siamese cat may become more vocal and playful during the heat cycle. She is more likely to seek out attention and will also be more affectionate. 

It’s best to take your cat to the vet if you suspect your cat is in heat, so you can get advice on how to handle the situation.
