When we had Abby spayed, they sent pain meds home with her - plus they gave her a good dose before leaving the Vet. She thought she was Wonder Woman. She felt really good (if you know what I mean) and had no pain - so the sky was the limit. Once the dose they gave her wore off, she got no more from us. Better she should feel a bit of discomfort and be quiet than to fly like a Wallenda!
