Over the weekend, I needed to bring my kitten Minerva over to our producer Jake's apartment, which required us going on a subway. I wanted Minerva to have the option of seeing where she was going as well as curling up and sleeping, so I bought this carrier! The Pettom Bubble Backpack has a bubble attachment that screws on, giving your little dog or cat a way to see out! (You can also screw on a flat screen so the backpack fits under an airline seat.) The backpack has tons of air holes for your little buddy and a soft insert to put at the bottom of the pack so they have a cozy place to sit or lie. Plus, they come in a bunch of different colors! (Just a head's up: Minerva is about 5 pounds and she was almost too big for the backpack, so this is definitely for tiny dogs and cats!)
