I was reading the comments on a buzzfeed "exotic pets" video on youtube and some people we're commenting on how they said something about that rats may bite. They commenters were saying "Oh a rat will ONLY bite if you did something wrong" Have they never owned a rat? I had never mistreated Jojo in anyway shape or form or did anything to scare him yet I still got bitten a couple times. I assume it was because he was mistreated at the pet store that I got him from. One person put up the argument that "They only live 3-4 years so they can't develop fear from being mishandled at a pet store and such" ...really? A LOT can happen in 3-4 years. So basically they're saying "Oh a rat can learn all this complicated tricks and such but they can't develop a dislike towards something."
