Maggie was spayed when she was 8 years old and lived to be 14 almost 15

Shadow and Keesha were spayed at 6 months
Eli and Ozzy were neutered around 7-8 months
Sheeba was spayed around 15 months because i thought she was already spayed but she just was really late coming into heat and didnt have her first heat(that i knew of anyways) until she was 15 months old
