* Check for a scar on the abdomen. If the ferret has been spayed, there will be a small scar on the abdomen where the uterus and ovaries were removed.
* Look for the presence of nipples. If the ferret is not spayed, she will have eight nipples located on her belly. If she has been spayed, her nipples may be smaller and less noticeable.
If you are not sure whether or not your ferret is fixed, you can take them to a veterinarian for a checkup. The veterinarian will be able to tell you for sure if the ferret has been fixed or not.
