I've never had any problems getting my pets spayed/neutered. I've always had it done at the Humane socitety. They operate in the morning and then you pick them up in the evening. Tibby my female was just kind of groggy that night, but the next day she was fine. She wasn't as active as normal but she acted fine. Corkscrew (my male) he was slightly less groggy that night but the next morning he was acting like nothing happened.
