At present, many owners choose to spay their pet cats, firstly to avoid some unnecessary troubles, and secondly, for pets, spaying can prevent diseases of the reproductive organs. However, some people report that after spaying their cats, they still exhibit heat behavior. So what exactly is going on?

　　First, you need to be clear about which spaying method was used on your cat. There are three types of cat spaying methods: tubal ligation, ovary removal, and simultaneous removal of the uterus and ovaries.

　　If it is only simple tubal ligation, the cat will still go into heat after spaying and mating is still possible. If only the ovaries are removed, heat behavior may also appear. Only when both the uterus and ovaries are removed simultaneously can heat behavior possibly be eliminated. But it is not absolute; when other glands malfunction and affect the cat’s endocrine system, heat behavior may still occur.

　　Secondly, under what circumstances will a cat that has had its uterus and ovaries removed still go into heat?

　　1. Proliferation after ovary cell detachment, which occasionally happens. To confirm if this is the cause, an abdominal ultrasound and cavity exploration, along with pathological tissue sections, are needed for diagnosis.

　　2. Adrenal gland abnormalities can also cause a female cat to go into heat after spaying. This requires ACTH stimulation tests, abdominal ultrasound, and pathological biopsy for confirmation.

　　If a spayed cat goes into heat again, the owner must pay attention and manage the cat carefully during this time to prevent contact with tomcats.
