I don't think we can say this too much but Kiwi is adorable. I talked to 3 vets about a good time to have Sissy spayed (had to travel to 3 different towns to get 3 vets) One said 6 months the other 2 said 5 months so I split the difference and did it at almost 7 moths lol. All 3 said that though it used to be thought that waiting until after 1 heat was best, they now know that there is no need. If your vet is comfortable with Kiwi's weight then she should be fine. As everyone else has said, ask questions and let the vet erasure you.
I had a chihuahua that I couldn't get spayed because of a heart murmur, she never had a litter and she passed on at 14 from a mamory tumor. So the alternative to not getting her spayed is very dangerous.
My bet is that the worse that will happen from the operation is a few more grey hairs for Mom.
