Spaying (females) and neutering (males) are widely recommended surgical procedures to maintain feline health, prevent behavioral problems, and prevent unwanted breeding. In Japan, this procedure is routinely performed at many veterinary clinics, and undergoing surgery at the appropriate time can significantly improve a cat's quality of life.
Why Is Surgery Recommended?
Prevention of reproductive system diseases (pyometra, mammary tumors, testicular tumors, etc.)
Reduced risk of traffic accidents and infections (feline AIDS, feline leukemia) from not venturing outdoors
Social responsibility in preventing unwanted litters and reducing cat suffering
Optimal Timing for Surgery
Spaying (Female Cats)
Recommended Age: Around 6 months old (ideally before the first heat)
Studies show that surgery before the first heat can reduce the risk of mammary tumors by approximately 91% (74% reduction if performed after the first heat, 14% reduction after two or more heats).
However, considering the impact on skeletal growth, many veterinarians recommend waiting until the cat weighs at least 2–2.5 kg (typically between 4–6 months of age). For larger breeds like Maine Coons, some vets recommend waiting until around one year of age.
Signs of Heat (Indicators for Urgent Surgery)
Excessive affection and increased purring
Low, distinctive prolonged meowing (calling)
Rubbing her body against floors and walls
Treading with hind legs and raising the hindquarters
Once heat begins, surgery is typically performed after the heat cycle subsides (increased bleeding and congestion risk during heat).
Neutering (Male Cats)
Recommended Age: Between 6–8 months old (after the testicles have descended)
In male cats, the testicles descend into the scrotum around 4–6 months of age (consult your vet if testicles fail to descend). Neutering helps improve the following behavioral problems.
Spraying behavior (urine marking): Depositing strong-smelling urine on walls and furniture
Territorial aggression
Roaming and escape impulses
Obsession with females in heat and excessive vocalization
While spraying may not completely disappear after neutering, improvement is seen in approximately 85–90% of cases (behavior that was established before surgery may persist).
Surgical Procedure and Process
Spaying Procedure (Female Cats)
Procedure: Under general anesthesia, the ovaries (or ovaries and uterus) are removed. This can be ovariohysterectomy (removal of both ovaries and uterus) or ovariectomy (ovary removal only); ovariohysterectomy is more common in Japan.
Surgery Duration: Approximately 30–60 minutes
Hospital Stay: Usually same-day or overnight
Cost Range (Japan): Approximately ¥15,000–¥40,000 (varies by clinic and region)
Neutering Procedure (Male Cats)
Procedure: Under general anesthesia or sedation, the testicles are removed through small incisions. This is a shorter procedure with minimal invasiveness compared to spaying, and typically requires no sutures.
Surgery Duration: Approximately 15–30 minutes
Hospital Stay: Usually same-day
Cost Range (Japan): Approximately ¥10,000–¥25,000
Pre-Surgery Preparation
Fasting: Typically no food for 12 hours before surgery and no water for 4–6 hours before
Pre-operative Examination: Blood work to confirm the cat is healthy enough for anesthesia
Regular vaccinations should be current before surgery
Post-Operative Care
Day of Surgery Through Several Days
Keep your cat quiet while recovering from anesthesia (watch for unsteadiness and hypothermia)
Use an Elizabethan collar to prevent licking of the surgical site
Check the incision daily for redness, swelling, discharge, or opening—contact your vet immediately if any occur
Restrict strenuous activity and jumping for 1–2 weeks
Long-Term Dietary Management
After spaying or neutering, basal metabolism decreases by 20–25%, making obesity more likely.
Switch to a low-calorie spay/neuter formula diet after surgery
Reduce food portions by approximately 20–30%
Monitor weight regularly and consult your veterinarian
Behavioral Changes
Common behavioral changes after surgery:
Increased calm and reduced aggression
Reduced spraying and marking behavior (especially in males)
Decreased interest in going outdoors
Surgery does not change your cat's personality or playfulness. In fact, cats typically become calmer and easier to live with.
Frequently Asked Questions About Spaying and Neutering
"Isn't surgery cruel to the cat?"
Cats do not consciously desire to reproduce the way humans do. For most cats, avoiding the intense stress of heat cycles (constant vocalization and escape attempts) and the risk of reproductive disease is far preferable to temporary surgical pain in the long term.
"Should a cat have at least one litter?"
This is an unsupported myth. Whether a cat has given birth does not affect surgical benefits like mammary tumor prevention; in fact, earlier surgery provides greater preventive benefits.
"Is surgery unnecessary for indoor cats?"
Indoor cats still experience heat-related behavioral problems (especially excessive vocalization), hormonal stress, and reproductive health risks. Surgery is recommended for indoor cats as well.
Feline spaying and neutering are safe procedures when performed at the right time by a qualified veterinary clinic. Consult with your veterinarian to determine the best timing for your cat.
