its a shame Kevin did what he did, even if the rat was a little aggressive just giving up is not the answer you cant just give up on an innocent life and then decide you want to get more! plus just releasing him into the wild is totally the wrong thing to do! you should have taken him to a rescue place even if its out of the way he would have been safe warm and happy god knows what happened to the poor little guy! i wouldn't suggest getting anymore rats because this guy might just get bored, give up and release them!
