Gingerbread is getting neutered this Thursday and I'm really nervous. [

] He just turned 1 year old and we actually took him to be neutered when he was about 7 months old. They did the bloodwork and his potassium level was high. His heart also showed an arrythmia on the EKG. Sooo, they called me to come get him.
We took him back a couple of days later and this time his potassium was normal, but the sodium was slightly off. The vet said that it should be fine to go ahead and schedule the neuter and also that an arrythmia could be "normal" for Gingerbread. Needless to say, I've haven't been able to bring myself to schedule that neuter until now. Gingerbread is my little angel and I'm so scared to lose him! He came from a petstore (not doing that again) so I don't know anything about his medical history. [&o]
He's scheduled to be neutered this Thursday and of course they'll do bloodwork again before the surgery. I haven't been going to this vet for long, but I chose them because they have all the latest equipment and seem very responsible. Bloodwork is actually mandatory for ALL animals before surgery, they have a heated surgery table, an iv in place during surgery, heart monitor, respiratory monitor, etc.
I feel sick to my stomach thinking about him being neutered 4 days from now! So I guess what I need to know is whether I'm overreacting and I could really use some words of encouragement. [&:]
