I think the laser surgery is fantastic, I just don't see the need for two nights??
You will have to withhold his food and water the night before, but I'm pretty sure you can handle that
You also have to keep him quiet and no jumping (most important that first night), but I'm pretty sure you can handle that also.....
You need to call and actually speak with your vet before you agree to that, unless you're ok with him being there two nights.
