The newer gas is sevoflurane its suppose to be even safer than isoflurane. I know this cause we went to vet last sat and got some blood work. I am goin have Hayley spayed by laser also its suppose to be a lot less bleeding and pain than triditional way. Vet told me also that they heal a lot faster. I am sure they do this for neutering also. Hope this helps ya
