We have all had the same fears and worries. That's why the vets here encourage everyone to research, research, research. Some people have complications including death. Some, like me, had no issues whatsoever. Any surgery has risks, in fact just going outside or driving your car is a risk, but we have faith that we know the dangers and we are prepared. Have faith in your surgical team, follow their recommendations and you should be fine but there are no guarantees. I also thought about writing letters but I never did. Do what you feel you want to do about that. I wish you all a happy and healthy journey!!!
