I ran across this a while back...
"
Laparoscopic Spays are a revolutionary new technique for performing both ovariectomies and ovariohysterectomies in female cats and dogs. Performed through one to three small incisions in the abdomen rather than a large incision it offers a less painful, faster healing alternative to traditional spays. A study published in the 2005 Journal of the Veterinary Medical Association concluded laparoscopic spays caused less surgical stress and up to 65% less post-operative pain than a traditional open surgical spay."
I'd give credit for the above, but, I can't remember where I got it.
Anyhow, seems like this is a lot more "gentle" way to get this done.
Just one/few small incisions to heal.
