Cubby was fixed at 6 months old, my vet charged me 45$ to get it done. He had to stay over night because the medication they gave him was to much for his system. They gave him the correct amount according to age/weight, but it was to much for him. After I brought him home they told me not to let him jump. I let him out of his jail cell and went to bed I woke up to a purring Cubby staring right at me on the bed. He jumped up there on is own. When you have your future cats done try to make sure they don't jump.
