Ideally, pets are spayed or neutered between the ages of 6 to 12 months. The benefits of spaying female cats or dogs include: reducing the risk of mammary cancer by 95 percent; preventing uterine infections; eliminating heat cycles and preventing unwanted pregnancies. The procedure consists of removing the ovaries and uterus. The benefits of neutering male cats or dogs include: reducing the risk of prostate and testicular cancer; preventing roaming; preventing aggression and marking and reducing urine odor. The procedure consists of removing the testicles. A spayed or neutered pet will continue to have his or her own unique personality. With today’s modern anesthetics and monitoring equipment, the risk of complication is extremely low. The AMC requires a pre-operative examination and blood work prior to all anesthetic procedures, which includes spay and neuter procedures.
