Spayed cat vs neutered cat – what’s the difference?

When adopting or raising a cat, the decision to spay or neuter them often becomes a key consideration. Many pet owners may be familiar with these terms but there is still confusion about what each procedure entails and how it affects a cat’s overall health and behaviour. Spaying and neutering are two types of sterilisation surgeries performed on cats, each designed to prevent reproduction. However, the differences between the two, their specific benefits and the post-operative care required for each can influence how a pet owner decides what is best for their cat.

In this comprehensive guide, we will explore the differences between a spayed cat and a neutered cat, examine the benefits of these surgeries, discuss when they should be performed and cover some of the common misconceptions associated with the procedures. Understanding these factors can help you make an informed decision about the long-term well-being of your feline companion.

What does spaying a cat mean?

Spaying a cat is a surgical procedure performed on female cats to remove their reproductive organs, typically the ovaries and sometimes the uterus. This is called an ovariohysterectomy. By removing the ovaries, the cat’s body no longer produces estrogen or progesterone, the hormones responsible for the heat cycle and reproduction. The result is that a spayed cat cannot become pregnant and she will not go into heat.

Spaying is a routine procedure performed by veterinarians worldwide and has been proven to offer significant health benefits beyond just preventing pregnancy. In fact, cat spaying can extend a cat’s life and prevent several serious health conditions.

The benefits of spaying a cat

The decision to spay a female cat offers numerous advantages, both for the individual cat and for the overall feline population. Below you can find some of the most notable benefits of spaying a cat:

  1. Eliminating heat cycles: One of the most immediate benefits of spaying a cat is eliminating heat cycles. Cats in heat can exhibit a range of behaviours that can be difficult for pet owners to manage, such as loud yowling, restlessness and increased attempts to escape the house. By spaying, these behaviours are no longer a concern, making life more peaceful for both the cat and the owner.
  2. Reducing the risk of cancers: Spaying significantly reduces the risk of developing mammary gland tumors, one of the most common and aggressive cancers in female cats. Additionally, by removing the ovaries, the risk of ovarian cancer is eliminated and the likelihood of uterine cancer is also greatly reduced.
  3. Preventing unwanted litters: Overpopulation is a significant issue in the feline world, particularly with stray and feral cats. Shelters are often overwhelmed by kittens, and sadly, many never find homes. By spaying your cat, you prevent the possibility of unwanted pregnancies, reducing the burden on shelters and helping to manage the overall cat population.
  4. Improved behaviour: Female cats in heat can become agitated or even aggressive due to hormonal changes. Spaying helps stabilise their mood, leading to a calmer, more affectionate pet. A spayed cat is also less likely to engage in unwanted mating behaviours such as roaming or marking territory.
  5. Increased lifespan: Spayed cats tend to live longer, healthier lives. This is partly due to the reduced risk of cancers but also because they are less likely to engage in risky behaviours such as roaming or fighting with other cats, which can expose them to injuries and diseases.

Neutering a male cat: what it involves

Neutering a cat, also known as castration or orchiectomy, is the surgical removal of a male cat’s testicles. This procedure stops the production of sperm and significantly reduces testosterone levels in the body. Testosterone is the hormone responsible for many of the more territorial and aggressive behaviours seen in unneutered male cats.

By neutering a male cat, pet owners can prevent a range of problematic behaviours and contribute to their cat’s overall health and longevity. The procedure is routine, safe, and performed by veterinarians under general anesthesia.

The benefits of neutering a male cat

The benefits of neutering a male cat extend beyond just preventing reproduction. Neutered cats often exhibit better behaviour, improved health and a reduced risk of certain diseases. Here you can find some of the most important benefits:

  1. Reduced aggressionMale cat neutering is associated with a significant reduction in aggressive behaviour. Unneutered male cats are more likely to engage in fights with other cats, particularly over territory or access to females in heat. These fights can lead to serious injuries and the spread of infectious diseases such as feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV). Neutering reduces the testosterone-driven desire to fight, resulting in a more peaceful cat.
  2. Prevention of testicular cancer: Neutering eliminates the possibility of testicular cancer, a common concern for older male cats. Additionally, neutering reduces the risk of prostate problems, which can cause discomfort and urinary issues as a cat ages.
  3. Decreased marking behaviour: Male cats often spray urine to mark their territory, especially in multi-cat households or when they perceive a threat from another animal. This behaviour is driven by testosterone. Neutered cats are far less likely to spray, making them easier to live with and reducing the likelihood of destructive marking inside the home.
  4. Reduced roaming and mating behaviours: Unneutered male cats are driven to roam far from home in search of a mate. This can lead to them getting lost, injured, or involved in traffic accidents. Male cat neutering reduces the instinct to roam, keeping your cat closer to home and safer from potential dangers.
  5. Improved focus on play and affection: After neutering, male cats often become more affectionate and focused on their relationships with humans and other pets. The absence of the strong mating drive allows them to redirect their energy towards play and bonding.

Female cat neutering: understanding the terminology

Although female cat neutering is often referred to as spaying, the two terms are sometimes used interchangeably in common language. Technically, both spaying and neutering fall under the category of sterilisation surgeries, with neutering more commonly associated with males. However, in the context of female cats, cat spaying is the specific term for the surgical removal of reproductive organs.

Spaying remains the more widely used term when referring to the sterilisation of female cats, but the underlying goal - preventing reproduction and improving health - remains the same. For clarity, when discussing female cat neutering, most veterinarians will use the term spaying to describe the procedure.

When should you spay or neuter your cat?

One of the most common questions pet owners ask is when the best time is to spay or neuter their cat. Generally, veterinarians recommend spaying or neutering before a cat reaches sexual maturity, which is typically around five to six months of age. Early intervention can prevent many unwanted behaviours, such as spraying in males or the constant vocalisations and restlessness of a female cat in heat.

There is also growing evidence to suggest that early spaying or neutering, as early as eight to twelve weeks of age, may provide even greater benefits in terms of preventing the development of reproductive behaviours. However, some veterinarians may prefer to wait until a kitten is slightly older to ensure they are strong enough to undergo surgery.

For older cats, it is still possible to perform spaying a cat or neutering a cat but additional considerations may be needed. Older cats may require more careful monitoring during surgery and recovery times may be slightly longer. Consulting with your veterinarian is essential to determine the best timing for your cat’s individual circumstances.

Signs your cat needs to be neutered

If you’ve adopted a cat or rescued one from the streets, you may not always know whether they have been spayed or neutered. Recognising signs your cat needs to be neutered can help you determine if surgery is necessary. Here are some key behaviours to look for, particularly in male cats:

  1. Spraying or marking: One of the most common behaviours in unneutered male cats is spraying urine to mark territory. This can happen both indoors and outdoors, and it often comes with a strong, unpleasant odour. Male cat neutering can drastically reduce or eliminate this behaviour.
  2. Increased aggression: Uncastrated male cats are more prone to fighting with other cats, particularly other males. These fights are often driven by the desire to establish dominance or win access to females in heat. If your cat is displaying unusually aggressive behaviour, especially towards other cats, neutering may help calm them down.
  3. Roaming and disappearing: If your male cat frequently wanders off for long periods or seems more interested in escaping the house than staying home, this may be a sign they are searching for a mate. Neutered cats are far less likely to roam, reducing the risk of them getting lost or injured.

Post-surgery care for spayed and neutered cats

The recovery process after spaying or neutering a cat is relatively straightforward but it does require some careful attention from pet owners. After surgery, your cat will need time to rest and recover, and there are a few key steps you should follow to ensure their comfort and safety:

  1. Provide a quiet, comfortable space: After surgery, cats may feel groggy or disoriented as they recover from anesthesia. It’s important to provide a quiet, comfortable space where they can rest without being disturbed by other pets or loud noises. A soft bed and a warm blanket can help keep them cozy.
  2. Monitor the incision site: For both spaying and neutering, your cat will have a small incision that needs to be monitored for signs of infection. Look for any redness, swelling, or discharge, and contact your veterinarian if you notice anything unusual. Most incisions heal within 10 to 14 days but keeping an eye on the site is crucial during this time.
  3. Prevent licking or scratching: Cats often try to lick or scratch at their incision site, which can lead to infection or reopening of the wound. A cone or Elizabethan collar can prevent your cat from accessing the area. Some pet owners opt for post-surgical suits, which cover the incision site and prevent licking while allowing the cat to move more freely.
  4. Follow your vet’s feeding instructions: After surgery, your cat may not have a strong appetite for the first day or two. Follow your veterinarian’s instructions for when and what to feed your cat, and make sure they have access to fresh water. Gradually reintroduce their normal diet as their appetite returns.

Long-term benefits of spaying and neutering

Both spaying and neutering a cat offer substantial long-term health benefits. By preventing reproductive-related diseases such as cancers of the reproductive organs, these procedures contribute to a longer, healthier life for your cat. Additionally, the reduction in hormone-driven behaviours such as aggression, spraying and roaming leads to a more peaceful and harmonious household.

Beyond individual benefits, spaying and neutering also contribute to the larger goal of reducing the number of unwanted cats in shelters and on the streets. Overpopulation is a serious issue in many regions, and spaying or neutering your pet is one way to play an active role in controlling the feline population.

Addressing common myths about spaying and neutering

Despite the clear benefits, some myths about spaying and neutering a cat persist. These misconceptions can sometimes prevent pet owners from making the best decision for their cat’s health. Let’s address a few of these myths:

  1. “Spaying or neutering will make my cat fat.” While spayed or neutered cats may have a slightly reduced activity level, this does not automatically lead to weight gain. Obesity is typically caused by overeating and lack of exercise, not the surgery itself. With proper diet and regular playtime, your cat can maintain a healthy weight post-surgery.
  2. “Spaying or neutering will change my cat’s personality.” While the surgery can lead to changes in behaviour, such as reduced aggression or spraying, it will not change your cat’s core personality. Your cat will remain affectionate, playful, and curious, just as they were before the procedure.
  3. “It’s better to let my cat have one litter before spaying.” This is a common myth, but there is no medical or behavioural reason to let a cat have a litter before spaying. In fact, early spaying offers the best protection against reproductive cancers and other health issues.

Conclusion: making the right choice for your cat

Deciding whether to spay or neuter your cat is one of the most responsible and caring decisions you can make as a pet owner. Spaying or neutering a cat provides numerous health, behavioural, and population control benefits, all of which contribute to a happier, healthier life for your feline friend. By understanding the differences between a spayed cat and a neutered cat and by working closely with your veterinarian to determine the best timing for surgery, you can ensure that your pet enjoys a long, fulfilling life.
