Just saw this - good to hear Buddy slept well! My Castor went through the soft palate and nares surgery in November. He stayed over at the hospital but after that didn't get any pain killers, just meds for acid reflux. He threw up a lot after a day or so at home (and couldn't keep the medicine down), so we put him a bland diet of boiled rice and chicken for a week.
Wishing Buddy a speedy recovery!
