Katie, go take yourself a nap, and calm your meowmie (and all of us down for a while please). Anesthesia can throw a cat off for quite a few hours until it starts leaving their system. Best you can do is keep a peek on Katie, and keep her calm. I've had cats that have had medical procedures done late in the day (emergencies have to be priority) and brought them home looped. They stay in the carrier until they seem to be fully awake, but if they are WUI (walking under the influence) it's back into the carrier until sober.
