Irresponsible. You can't let an animal leap up the food chain like that, no matter how adorable. If we encourage our kittens and small dogs to act like sharks, they'll become drunk with power and murder us all. Additionally, strap-on fins have no business being on housepets. They should only be used by consenting adults who share a Finding Nemo fetish and that's it (Dan Savage calls it "Finning"). In closing, we've never watched "Shark Week," but we'd watch the holy hell out of this.
