Wow! A backpack for a pet?? Nice hunt @steemhuntsman! I've been wanting a cat, and when I buy or adopt one, I might bought one of this too.
Pros:

• you can bing your pet wherever you want too.
• more bonding time for both of you
• there are air holes for ventilation so you won't have to worry about your being suffocated
• your pet can enjoy the outside view

Cons:

• none so far
