We have always stayed and held them in our arms. All but the last time, when they wouldn’t let us. This was not at our vet’s but at the Animal Rescue, where a well-meaning neighbor had sent our old, ailing cat, thinking he was a stray, thus putting him out of reach of our care and medicine. It took us three days to find him, and by then we were too late to save him; he was literally killed by kindness.
