Opinions are like assholes. Everyone has one. I say ignore the idiots.
Side note: We recently had to euthanize our kitty-son Dooley, at fifteen years old. It was one of the worst days of my life in recent memory as my husband was in the ER and I had to go on my own. As hysterical and saddened as I was, that's how calm and empathetic the staff at our vetinary clinic was. we've been eeing the same vet for over 23 years and he has brought peace to seven of our babies, often with tears in his own eyes, so I do know what the job entails and am grateful that there are people like you to do it.
