Everyone tells me I should get into a line of work dealing with animals. Well, a vets office is out of the question. Years ago while waiting in the lobby a family came in to have their dog PTS. I cried right there.
More recently I went to pick up meds or something at my vet and heard a woman crying hysterically. The receptionist told me she just had to have her dog put down. I couldn't even talk. I had to step back and she handed me a tissue to wipe my eyes. Even now while I'm typing this my eyes are filling up.

RIP to the kitties in the ER. They are all free of pain now.
