Good luck for Wednesday. I have one of mine going in tomorrow (well, I say mine, but really a foster), so feel the anxiety you feel. Hopefully Mario will be fine and it will go smoothly. I've written an article about before, during and after a spay/neuter, would you like me to PM it to you?
You're doing a great job for them both
