Before neutering a female cat, it is best for the owner to observe whether the cat is in estrus. If the cat is in estrus, sterilization surgery is not allowed. You need to fast and drink nothing before the surgery. Pet owners can prepare a blanket and a comfortable box for the cat. The space should be enough for the cat to lie flat. Then, they can prepare some wipes, cat eye drops, iodine, medical cotton swabs and other utensils; if the cat is awake after sterilization, Before feeding, you should lay it down flat and do not nestle it up to the neck to avoid suffocation. It is best to stay with the cat at all times and observe the cat's condition. Remember not to let the female cat do strenuous exercise to avoid straining the wound. If 2-3 days after the operation, the cat’s wound is found to have secretions, accompanied by an increase in body temperature and other symptoms, the pet owner should take the cat to the hospital for treatment in a timely manner.
