Public service announcement: if you make a video of your pet being put to
sleep, and show it to your gynecologist at your next appointment, your
GYN will immediately call her veterinarian friend and tell him all
about it, and they will mock you a second time. It's one thing to want a record of Kitty's passing for your own personal viewing, or maybe to share with one of Kitty's loved ones who was unable to attend the last vet visit (although in about fifteen years of practice, not once has any of my own clients made such a recording!). But showing the video around to all and sundry smacks of "Kittycat snuff video" to me. It's just not socially acceptable.
