From 2065438 to 2007, the American Veterinary Association (AVMA) formally adopted the recommendations of the Veterinary Working Group on the Space Age and Sterilization.
In this document, it is suggested that cats that do not intend to breed should be sterilized (FFF) before 5 months old.
This document has been approved by American Cat Doctor Association, American Animal Hospital Association, Winn Foundation, Cat Lovers Association and International Cat Association.
Why sterilization before sexual maturity?
The concept of sterilization before sexual maturity is basically the same in international authoritative organizations, and the main controversy lies in the difference in the control of estrus time.
The cat group advocates surgery at about 4 months old, and the American Veterinary Association (AVMA) advocates surgery before 5 months old.
In the past, the traditional sterilization time was about 6 months, but in recent years, with the attention to the phenomenon of "precocity" of cats and the improvement of anesthetic drugs and surgical techniques, the operation time should be advanced.
Sterilization of cats before sexual maturity can reduce the incidence of breast cancer, uterine empyema and dystocia, and reduce potential behavioral problems.
In addition, early surgery also has the advantages of reducing intraoperative bleeding, cats being more sensitive to anesthetics and painkillers, recovering quickly after surgery, fewer complications and avoiding unintended pregnancy.
If you decide to keep a cat at home, arrange sterilization about 2~3 weeks after vaccination (at this time, it is almost 4~5 months old).
The following is the sterilization schedule recommended by Cat Group according to kittens from different sources in 2006 for your reference.
1. Weight limit
More than 5,6 kilograms
2. Preoperative requirements
Eight hours without food and water.
3. Postoperative requirements
Continue to ban water for 3 minutes and fast for 8 minutes. (The specific doctor will talk about it)
4. What do you need to prepare?
Elizabeth Hood (anti-licking male cat)
Disinfection clothing (female cat, anti-licking)
Urine pad (to prevent incontinence and vomiting, bring more)
Air box (cat bag is not recommended)
Eye drops (dry eyes after anesthesia)
5. Is preoperative examination necessary?
If the cat has been in good health, it is recommended to have a blood routine. Of course, it is better to do a biochemical examination if conditions permit.
6. How to choose anesthesia?
It is safer to do respiratory anesthesia when conditions permit. Acupuncture anesthesia is also possible, but there is a small chance that cats will be allergic to anesthesia, and acupuncture anesthesia is difficult to save.
It is normal for cats to disown their parents when they wake up from surgical anesthesia. Ignore it, just keep the cat quiet and avoid hurting yourself by mistake. It will be better in about 12 hour. At this moment, it is suggested that the cat be kept in a cage, and it is forbidden to walk and pull the wound, so that it can be released the next day.
7. Do you need to be hospitalized?
It depends. Generally speaking, it is not necessary, because unfamiliar environment will make cats more afraid and stressed.
8. Take out stitches?
Now many hospitals can do minimally invasive surgery, and there is no need to go back to the hospital to take out stitches. Just ask before the operation. It also reduces the stress risk of cats without secondary stitching.
9. Anti-inflammatory?
General hospitals will inject long-acting anti-inflammatory needles. After the owner brought the cat home, he didn't have to take care of the wound for the first 4 days. On the fifth day, he can apply a little iodophor to the cat's wound. Be sure to avoid cats licking wounds!
10. analgesia
The general hospital will give the cat a long-acting analgesic injection, but there will still be more or less pain. Don't worry too much. Generally, the male cat will be alive and kicking on the third day and the female cat will be alive and kicking on the fourth day.
1 1.
Don't feed too much for two days after operation, eat less and eat more meals, so as not to upset the cat's stomach and may vomit after eating.
12. Bathtub
Generally, it is best to take a bath before surgery. It takes two weeks for the male cat and one month for the female cat to take a bath after the operation.
PS:？ male cat
Male cats can also have surgery when they are in estrus.
& lt 1 & gt； Boys' operation is actually very easy, and the operation process can be completed in 10 minutes.
& lt2> In order to prevent the cat from licking the wound after operation, it is necessary to wear an Elizabeth mask, which will make it difficult for the cat to eat and drink. You can temporarily remove it when eating, but you must not be soft-hearted. After eating, be sure to take it back until the wound heals.
& lt3> Boys are in good mental state after sterilization for about 3 days, and their wounds can basically recover in 7 days.
Androgen will gradually fade after sterilization of<4>, and it is still possible for a female cat to get pregnant within three months. Moreover, there is indeed the phenomenon of instinctively riding a female cat, so don't be too alarmed, so if the female cat is in estrus, it is still necessary to pay attention to isolation.
& lt5> is sterilized without balls, and Tintin is still there ... so it is normal for kittens to show pink Tintin. However, if there is still obvious estrus, we should consider whether there is no sterilization, there may be cryptorchidism, and we need to go to the hospital again for examination.
Boys can take a bath two weeks after operation.
Ps: female cat
The female cat is in estrus and needs to wait until the estrus is over before surgery.
& lt 1 & gt； The operation for girls takes about 30 minutes.
It is recommended to ask the doctor before operation whether it is tangent or lateral incision. Personally, I suggest a transverse incision. The wound is smaller and easier to recover. However, lateral incision is a test of doctors' skills, so some hospitals will tangent when they operate on interns, so it is better for everyone to ask clearly.
& lt2> In order to prevent the cat from licking the wound after operation, it is necessary to put on a disinfection suit for the cat. Generally, female cats don't need to wear Elizabeth condoms unless they really bite the sterilization suit.
Sterilization of<3> girls will be hard, and their mental state will be better in about 4 days, and the wound recovery will take 10 days.
Generally, the wounds of female cats need not be taken care of for the first 4 days, and it is enough to apply iodophor on the fifth day.
& lt4> Similarly, although the female cat will not have cryptorchidism, some doctors with poor skills will accidentally leave a small amount of ovarian tissue, which will still cause the cat to heat again. However, this kind of situation is rare, and the treatment method is the same as that of male cats.
? & lt5> Girls can take a bath one month after operation.
1. Does premature sterilization affect bone development?
Not exactly.
Sterilization of cats before sexual maturity will not hinder bone development.
The hormone that promotes the growth of cat bones is growth hormone secreted by pituitary gland. After cats enter puberty, under the action of sex hormones, bone scales close and long bones stop growing. (precocious bipeds are short for the same reason. )
If the sterilization time is earlier than sexual maturity, it will delay the closing of scales and the long bones of cats will continue to grow, so theoretically their body length and height are higher.
2. Does premature sterilization affect urethral development?
Not exactly.
Sterilization of cats before or after sexual maturity does not affect the diameter of urethra.
Sterilization mainly affects the male cat's secondary sexual characteristics (penis prick, vulva shape and "gills"), but these differences do not affect the cat's urination ability.
So it won't affect
In 199 1~ 1992, the research conclusions made by the College of Veterinary Medicine of the University of Minnesota and the Department of Small Animal Clinical Science of the University of Florida show that the conclusions are negative.
3. Is the female cat sterilized after giving birth to the baby?
That's bullshit！
Medical evidence is just the opposite. Sterilization before estrus can prevent 95% cats from developing breast tumors.
4. Male cats after sterilization are more susceptible to lower urinary tract syndrome?
Not exactly.
The occurrence of lower urinary tract syndrome is mostly in obese male cats, and some of them are indeed sterilized male cats. However, this is because the level of sex hormones after sterilization is reduced, which is easy to increase the appetite of cats and reduce the amount of exercise, which is more likely to cause obesity. Whether cats can control their carbon intake is ultimately the owner's problem.
Sterilization will not directly lead to obesity, but the biggest hidden danger is that after sterilization, eating habits will not be changed and exercise will not be encouraged. Not only sterilization, but also the popular "chubby" aesthetic is a hidden danger of the disease.
5. Chemical methods are safer?
Not exactly.
The so-called chemical method mainly uses hormones to reduce the estrogen level of cats, or to increase the progesterone level and delay estrus. This method can't solve the problem fundamentally, and it is easy to cause reproductive system diseases and liver and kidney function damage if used for a long time, with great side effects, so doctors don't recommend it.
6. Is the operation cruel and bloody?
No, it's just a minor operation.
It is necessary for shovel officer to consider the risk of operation when considering the operation, but it is suggested to make a decision from the perspective of weighing the advantages and disadvantages of both the cat and shovel officer.
With the gradual development of medicine, many risks and complications are under control, and we must not give up eating because of choking. European and American countries have also been vigorously developing non-surgical sterilization and contraception methods. I believe kittens can experience less pain, live happier and live longer in the future!
7. Why don't you suggest cleaning your teeth at the same time as sterilization?
The process of tooth cleaning involves a high degree of bacterial contamination: after tooth cleaning, millions of bacteria in teeth and gums will be released into the blood and surrounding tissues of animals, which is the characteristic of this operation. Sterilization and plastic surgery are the most common cleaning operations, and the risk of bacterial contamination in the operation itself is extremely small. Therefore, separate surgery can greatly reduce unnecessary surgical infection. Similarly, cats with serious infections, skin diseases or diarrhea should be cleaned after being cured.
8. Can't you be sterilized during estrus?
When the female cat is in estrus, the blood vessels in the ovary and uterus are congested. These tissues are more "fragile" than usual, and they are more likely to be injured during the operation, resulting in excessive bleeding. In addition, non-reproductive organs (such as skin, fat, muscle) are more likely to bleed during and after surgery than during estrus, which increases the risk of bleeding during surgery and the difficulty of postoperative recovery. Therefore, for cats that miss sterilization before the first estrus, veterinarians usually recommend sterilization at 1-2 weeks after estrus. The cat is in estrus, please don't use any banned powder. If someone recommends you to buy it, please stay away from him.
