Sugar was 3.5 pounds when she was spayed ~
the second time 
Long story, but when she was re homed I was told she was not spayed and she had no scar. Dr opened her op and found only a uterine stump and closed her back up. That was a year and a half ago and she still has no scar!!
Curri will be scheduled for a spay soon. She isn't quite 3 pounds and is only 6 1/2 months old so we have a few months yet.
Ahi will do great
You are doing the right thing by getting blood work before hand. You have to put your trust in your vet and in yourself for making informed decisions
