hey Prima.....Mickey will be fine, he'll do great. When we got ours spayed/neutered...they had to stay over night at the vets, b/c thats just how our vet does it, but when we went bac to pic them up they sure were happy~! Also I think angry b/c we left them....lol. Im sure he will be grogy, tired, etc. I'll keep you n' Mickey in my prayers......keep us updated~! GOOD LUCK MICKEY~!
