Awwww, she is SUCH a dollbaby

She IS perfect

!!!
Glad the spay is out of the way, it's always scary but especially when they're this little.
I don't know if this is what's going on, but I've had several surgeries myself---Could be the nerves that were cut during the surgery are now reattaching---it zings for a second, almost like a bee sting or electrical shock

Could be what's making her jump suddenly like that. As long as you keep her from bothering her stitches she should be just fine. If you notice anything "off", though, definitely call the vet. Has her appetite returned, and is she drinking/peeing okay? Don't worry about bugging the vet, that's what they're there for

Call them if you feel anything isn't right, and ask
I'd also keep her from running around too much just yet. She may think she's all better, but there is lots of healing to be done and she should be kept calm for at least 10 days, two weeks is even better. I know both of my girls acted like they never had surgery, the very next DAY

I had to put them in their ex-pens to keep them from hurting themselves.
