Izzy has the laser done - our vet is on top of all the cutting edge procedures and he highly recommended I spend the extra $$ for this on Izzy. Yup - reduced pain, swealling and she does NOT have a scar and he said healing time is greatly reduced. She stayed over night (they have 24/7 care with heated beds!!). Picked her up at 1pm on Saturday and I would say Sunday morning you would never know she was spayed on Friday. For me - it was peace of mind that she would be in less pain and for the extra $45 or $50 that it was - it was worth it to me. Up to you totally of course.
