What, really? I don't even.
I never liked PETA, because they're quite ridiculous and extreme, but it seems to me like they're really running out of things to do, so now they complain about virtual rats. Yeah, I get it, "video games make us violent" and "people get inspiration from video game violence". Bullshit. I've killed so many virtual animals in various games (I'm the only person in my Minecraft playing group that actively goes on a cow/sheep/pig killing rampages, and I even made an "animal trap" where all of them kept falling inside a hole and couldn't get out. It was hilarious, there were like 20 cows and 30 chickens in it) that PETA would probably lock me up somewhere and pray for the salvation of my soul. However, that's video games. In real life, I'm a vegetarian and I don't even kill bugs, let alone something else. I can shoot a tiger in the face in Tomb Raider, but I jumped in front of a running car to save a kitten from being hit by it. Hell, I kill people in video games. Would I kill someone in real life? No.
People are capable of distinguishing reality from video games. And if they're not, it was not the video games that caused it, there were problems prior to that.
