By Designer Brand Catspia, this revolutionary cat backpack allows your cat to have an enjoyable ride wherever you travel! The domed clear window allows your cat to enjoy the world going by whilst they still feel safe and secure in their own space. Inside the cosmonaut backpack the cat will be able to see the world around them and give them the ultimate happiness. It is really easy for you to wear either on your front or back and the adjustable straps allow a comfortable fit. Large ventilation holes ensure air circulation flow. May be suitable for some airlines but please check with your carrier first.
