my cat was an absolute menace and she weighed 4.8lbs at about a year old when the vet finally approved the spay because they wanted her to weigh 5lbs. She had snuck out & was pregnant so the surgery was really hard on her and she barely moved for months & got up to 9lbs. She has her energy back but doesn't go "demon mode" anymore or sneak out and she's not so chubby anymore.
