You got lots of great advice here! I would hope your vet is comfortable with the small ones, if not, it might be worth changing or at least asking which one of your vets does the small animals the most.
One more bit advice here; every animal reacts differently, some females bounce back right away, some not so fast.. it is like a hysterectomy in a woman.
Also, whatever pain meds they send her home with,
make sure you know all the possible side effects. so if she has a reaction, you will recognize it.
Ha, one more more bit of advise, lol.. Get a baby onesie, newborn or preemie, not only will she look cute in it,
, but you can put a sanitary pad in it over the suture site and she won't be able to bother it
