I already have some murder logs, but I don't consider them pets...I would never feed them because I don't want them to associate people with food.
I also have a lot of trash pandas that come visit. Once I had bought a rare peacock (it was a pure white bird...cost me $400), and I had him in a cage on my back porch to get him used to his new location before turning him loose into the flock. A "trash panda" paid a visit one night, and pulled that poor bird through the wish mesh a handful at a time, the only thing he couldn't get through the wire was the breastbone.
