Cat Neutering and Spaying Surgery Guide: Cost Estimates, Timing, and Hospital Selection You Need to Know in Sendai and Miyagi
Cat neutering and spaying surgery is a procedure that greatly contributes to extending healthy lifespan, preventing unwanted pregnancy, and reducing behavioral problems. In this guide, in addition to general medical knowledge, we place particular emphasis on explaining information specific to the Sendai City and Miyagi Prefecture area (cost estimates, subsidy programs, and points for hospital selection).

Medical Significance of the Surgery
Neutering Surgery (Male Cats):
This is a surgical procedure to remove the testicles. It is performed under general anesthesia, and the surgery typically takes 15–30 minutes. The main benefits are as follows:
- Prevention of testicular tumors and prostate disease
- Reduction of spraying behavior (marking)
- Decreased aggression toward other cats and dogs
- Reduction in roaming and escape behavior
Spaying Surgery (Female Cats):
The ovaries (and typically the uterus as well) are removed. The surgery takes approximately 30–60 minutes, and the recovery period varies depending on the size of the abdominal incision. The main benefits are as follows:
- Significant reduction in the risk of mammary gland tumors (research indicates approximately 91% risk reduction when performed before the first heat)
- Prevention of pyometra (uterine infection) and ovarian cysts
- Elimination of false pregnancy and hormone-related behavior
- Reduction in vocalization and stress behavior during estrus

Appropriate Timing for Surgery
General Recommended Period:
Surgery at 5–6 months of age is generally considered the standard timing. However, in recent veterinary medicine, early surgery "before the first heat (around 4 months of age)" is also becoming more common, and more veterinarians are recommending earlier timing, particularly from the perspective of preventing mammary gland tumors.
| Timing | Considerations |
|---|
| Around 4 months of age | High effectiveness in preventing mammary gland tumors (especially for females), faster post-operative recovery |
| 5–6 months of age | Generally recommended timing, body weight of 1.5 kg or more is a guideline |
| After first heat | Surgery is possible but the preventive effect against mammary gland tumors decreases |
| Adult cats (1 year or older) | Surgery is possible at any time and is effective even for individuals that have completed breeding |
Judgment as a Breeder:
For individuals that have completed breeding, it is recommended to proceed with surgery promptly after confirming physical fitness and health status, from the perspective of long-term health management.

Points to Consider When Selecting a Hospital in Sendai
Verify the quality of anesthesia management:
The greatest risk in cat surgery is anesthesia management. Check in advance whether the hospital uses "inhalation anesthesia (such as isoflurane)" and whether it continuously monitors heart rate, oxygen saturation, and respiratory rate during surgery.
Presence or absence of pre-operative blood testing:
A blood test before general anesthesia is important for detecting hidden organ diseases in advance. Choosing "no pre-operative testing, cheaper" is not necessarily the better value.
Emergency Response Capability:
Whether there is a system in place to respond if a problem occurs after surgery. It is reassuring to confirm whether the hospital is affiliated with a 24-hour emergency animal hospital.
Secondary Diagnostic/Emergency Response Hospitals in Sendai City (for Reference):
- There are multiple emergency response animal hospitals centered in Sendai City, Miyagi Prefecture. It is recommended to be aware of the nearest emergency hospital beforehand.

Basic Post-operative Care
Surgery Day – 3 Days After:
- Follow your veterinarian's instructions regarding food restrictions (typically fasting on the day of surgery)
- Keep the animal at rest in a small cage or room
- Continue wearing an Elizabethan collar despite resistance
- Prevent self-licking and scratching of the surgical site
4–7 Days Post-operative:
- Gradually return to normal activities
- Seek immediate veterinary attention if there is redness, swelling, or increased discharge at the surgical site
- Suture removal (7–10 days post-operative) if non-absorbable sutures were used
Post-operative Diet Management:
After neutering or spaying, metabolism changes and cats tend to gain weight. Within 1–3 months after surgery, it is recommended to switch to "post-operative neuter/spay diet" that is low-calorie and high-protein. Especially for males, the risk of urinary tract stones increases after neutering, so ensuring adequate water intake is also important.

Frequently Asked Questions
Q. Will problems really occur if surgery isn't performed?
Unneutered males tend to leave the house during mating season and not return, increase aggression toward other cats and owners, and establish spraying behavior. Unspayed females tend to be highly fertile, and the risk of reproductive system disease increases significantly.
Q. Can surgery be performed on older cats?
Surgery is possible even in cats 10 years or older if pre-operative testing shows no problems. However, anesthesia risk increases with age, so more careful testing and anesthesia management are required.
Q. Can multiple cats have surgery on the same day if you have several?
Some hospitals perform surgery on multiple cats on the same day. However, since post-operative care overlaps, some hospitals recommend spacing out surgery 1–2 cats at a time considering the owner's burden. Discuss this in advance.
