Just to be clear I don't like what they did to these animals but there has to be a reason. Were they at a shelter abandoned? Every animal shelter tries to adopt out their pets but often times they have to put them down because no one wants them.

I'm human like everyone else. It's easy for me to get attached to anything i.e. a bird, reptile, fish, a plant but I just don't need the burden of taking care of it.
