Why Spaying Is Recommended for Female Cats
Spaying — the surgical removal of a female cat's ovaries and uterus (ovariohysterectomy) or ovaries alone (ovariectomy) — is strongly recommended by veterinary organisations across Europe, including WSAVA and FECAVA. It is one of the most routinely performed veterinary procedures and, when carried out at the appropriate age by a qualified vet, is considered very safe. The health benefits for your cat are substantial, and spaying also plays an important role in reducing the population of unwanted and stray cats across the continent.
Europe faces a significant stray cat problem. It is estimated that tens of millions of unowned cats live across the EU, many of them in difficult conditions, particularly in southern European countries such as Greece, Romania, Spain, and Italy. Responsible pet ownership, including spaying, is an important part of addressing this issue at an individual level.
Health Benefits of Spaying
Pyometra Prevention
Pyometra is a potentially fatal infection of the uterus that is one of the most common serious conditions in intact female cats. It occurs when the uterus becomes filled with pus, often in the weeks following a season. Cats with pyometra can deteriorate very rapidly and frequently require emergency surgery. The condition is entirely preventable through spaying, which removes the uterus and eliminates the possibility of this life-threatening infection.
Reduction in Mammary Tumour Risk
Mammary tumours are unfortunately common in intact female cats, and the vast majority — around 85 to 90 percent — are malignant. Research consistently shows that spaying dramatically reduces the risk. Spaying before the first season reduces the risk of mammary tumours by approximately 91 percent. Spaying after the first but before the second season still offers around 86 percent risk reduction. After the second season, the protective effect diminishes, though some benefit remains. This evidence strongly supports early spaying as a preventive health measure.
Elimination of Reproductive-Related Conditions
Spaying prevents ovarian cysts, uterine infections, and the hormonal fluctuations associated with repeated oestrous cycles. Intact female cats can cycle repeatedly throughout the breeding season, which is prolonged in domestic indoor cats exposed to artificial light. These repeated cycles place hormonal demands on the body and, in some cats, cause persistent calling behaviour that can be very distressing for both cat and owner.
The Procedure and Recovery
Spaying is performed under general anaesthesia and typically takes between 30 and 60 minutes, depending on whether an ovariohysterectomy or ovariectomy is performed. Your cat will need to fast from food (but not water) for a period before the operation, as advised by your vet. Most cats are admitted in the morning and can return home the same evening.
Recovery at home typically takes 7 to 10 days. During this time, your cat should rest as much as possible and be prevented from jumping or engaging in vigorous play. An Elizabethan collar (the cone-shaped buster collar) is often recommended to prevent your cat from licking the wound, which can introduce infection. Dissolvable sutures are commonly used, meaning no return visit is required to remove stitches, though a follow-up check is still advisable to confirm healing is progressing well.
Signs of a complication to watch for include swelling, discharge, redness around the incision site, lethargy beyond the first 24 to 48 hours, loss of appetite, or any sign of pain. Contact your vet promptly if you notice any of these.
Best Age for Spaying
The traditional recommendation across much of Europe has been to spay cats from around five to six months of age, before their first season. This timing maximises the protective effect against mammary tumours and prevents any unwanted pregnancies, since cats can become pregnant at their first season.
Some rescue organisations and veterinary practices in Europe carry out early neutering at 8 to 16 weeks of age. Research has shown that cats neutered at this age recover very quickly and do not appear to suffer adverse long-term health consequences, though it remains less widely practised in general private practice. Discuss the best timing with your own vet, taking into account your cat's breed, body condition, and health status.
Addressing Common Owner Concerns
Will Spaying Cause Weight Gain?
This is one of the most frequently raised concerns, and it has a basis in fact. After spaying, a cat's metabolic rate reduces and her energy requirements decrease. If her food intake is not adjusted accordingly, she is likely to gain weight over time. However, weight gain after spaying is not inevitable — it is manageable with appropriate portion control and regular monitoring of body condition. Switching to a neutered cat formula food, which is slightly lower in calories and often higher in protein, can help. Maintaining a healthy weight is extremely important for your cat's long-term joint health, kidney function, and quality of life.
Will Her Personality Change?
Spaying does not fundamentally alter a cat's personality. Your cat will retain her individual temperament, habits, and affectionate behaviours. What does change is the elimination of hormonally driven behaviours associated with oestrus — the persistent vocalising, restlessness, and calling that intact females display when in season. For most owners, the removal of these behaviours is very welcome. Maine Coon and British Shorthair cats, which are known for their gentle and affectionate temperaments, typically settle into their personalities very well after spaying.
Is My Cat Too Old to Be Spayed?
There is no absolute upper age limit for spaying, though the surgical risk increases with age and the presence of any underlying health conditions. Older cats should have a pre-operative health assessment including blood tests to check organ function before being anaesthetised. If you have an older intact female cat, speak to your vet — in many cases, spaying is still both safe and beneficial, particularly if she is at risk of pyometra.
The Broader Picture
Spaying your cat is a decision that benefits her health, your household, and the wider community. By preventing unwanted litters, you are playing a part in reducing the number of cats that end up in rescue centres or living as strays. Across Europe, animal welfare organisations, municipalities, and veterinary bodies work together on trap-neuter-return programmes and public education campaigns to address the stray cat population. Your individual choice to spay contributes to this collective effort.
