it is SO nerve wracking when they go in- we've all been there!
She will be groggy when she comes home and depending on how she reacts to the meds she could be for a few days (layla doesn't react well so she took about 3-4 days to be back to normal). She needed to be carried outside to pee and i had to hold her little back end up- so pitiful
I used an infant onesie on her to keep her from licking her stitches- i only used this at night when i couldn't keep an eye on her.
