Why is your female cat drooling after spay operation?

An animal might drool within a few hours after surgery from the effects of the anesthesia. Sometimes the anesthesia causes nausea and vomiting. The nausea can cause drooling. Also, sometimes an animal can be slow to recover from the anesthesia, being dizzy, clumsey, and disoriented, which can also result in drooling. Keep an eye on her to see that she improves over the evening. These after-effects should wear off in a few hours. The cat should be fine the next day. If it is the day after surgery and she is still drooling, CALL THE VET.
