Gary's Instagram: @GaryTCat We bought the Giantex Astronaut Pet Cat Dog Puppy Carrier Travel Bag Space Capsule Backpack from Amazon in light green. Gary our Ginger Tabby is an indoor cat and loves going outside on adventures, but also gets a little nervous. The backpack seemed to make him feel pretty safe :) Although A little small, he seemed to be comfortable sitting upright, looking around and sniffing the air.
