Thanks for sharing everyone. They're good to read, it's nice to know animals are loved. I work with animals, and see so many bad things. I'm not allowed to mention abuse cases at work though.
The most traumatic thing I experienced was losing 3 of my bunnies to myxomatosis.
I had 9 bunnies at that time, and it's so contagious I was to prepare myself for losing all of them. Every day I woke up expecting to see more symptoms of myxo. I was very very lucky to "only" lose 3. They were all put down in the early stages, it's a cruel disease and I didn't want to let them suffer. I have mosquito wire, use revolution for mites and fleas, but it didn't work. I know of people with inside rabbits who have lost their bunnies to myxo as well, so no bunny is safe until we get a vaccine. I had depression for months.
Last year, we got so many bunnies dumped in our overnight pens with myxo, it was so depressing.
Also, looking after bunnies rescued from a meat farm is depressing/wonderful. Some don't make it so all you can be thankful of is their nice death and brief wonderful time outside of those cages. My remaining meat farm rabbit has twisted/arthritic forelegs, so I won't have him long-term
