I accidentally killed one of my gerbils when I was, like, 12 or 13. They had babies, which we were gonna give away as they got old enough to leave their mom. So, on a Saturday morning when it was still very early my dad's girlfriend at the time woke me up so I could get them ready and put them in a box for her to drop off at the pet store before work. Since they were difficult to catch I removed the cage from the plastic bottom thing (it was one of those cages seen below). When I was done I put the cage back on the bottom and went back to sleep. A couple of hours later I saw that the mom's head was outside the cage and her body inside, so I had basically beheaded her saying goodbye to her kids. I yelled for my dad so loud, he thought I was being murdered. I'll never get over it, tbh. I remember SOBBING my way through breakfast. Her name was Hermione.
