Hi...I just recently posted a similar question. I too have heard benefits for both. Although no scientific benefits fot not spaying. I have learned from reply's to my post spaying reduces the risk of cancer as well as other bad things. I have about decided to have my baby spayed but will have to find another vet. The vet I normally use keeps them overnight the night prior to surgery and sends no pain meds
Let me know what you decide and if you find any new info.
