Other forms: spayed, spaying
To spay is to operate on a female animal so she cannot breed. Get her spayed, spay the cat, spaying and neutering.
The pair of words is worth keeping straight: females are spayed and males are neutered or castrated. Done early it also lowers the risk of some cancers. The word comes from an Old French verb meaning to cut with a sword.
