Rita Thompson discusses a new, simple way to check if a female cat has been neutered.
Determining whether a female cat is neutered can be a challenge. Unlike males, there are no obvious signs, and early pregnancy is often undetectable. Traditionally, vets have relied on shaving the left flank to check for a tiny scar—usually just 2-3 millimetres long—or performing an exploratory laparotomy, an expensive procedure similar to a full spay. The only alternative has been to wait and see if she comes into season.
Fortunately, a new blood test is now available to determine neuter status in female cats. This test detects luteinising hormone (LH), a reproductive hormone released by the pituitary gland. In unneutered females, LH levels remain low, except during ovulation. Once a cat has been neutered, the removal of the ovaries disrupts hormonal feedback, causing LH levels to remain high. A reading above 1ng/ml in the bloodstream strongly indicates that a cat has been neutered.
The test is quick and simple, working much like a pregnancy test. A few drops of serum are added to the kit, and after 20 minutes, the results appear: One pink line means she is not neutered, Two pink lines mean she has been neutered.
This innovative solution saves time, money, and unnecessary procedures, making it a valuable tool for vets and rescuers alike.
