I'm sure little Kiwi will do just fine. I also have a little one...Roxi turned 1 in November. Last night I weighed her and she is now 2 lbs, 13 oz!! In August, Roxi was spayed, had teeth removed, liver biopsy and exploratory surgery (I think she weighed 2 lbs 3 oz at time of surgery). She did stay overnight, but her surgery was done at an Emergency/Specialty hospital and there is a vet and assistants there 24/7. Just wanted to let you know that there are other little ones who have had surgery and did just great
