My Storm loves her backpack.

Storm has used her backpack a couple times already to go to waterfalls and see snow in the Smoky Mountains. She has learned to sit on top and she knows it is her safe spot inside. Anytime, she gets nervous, she climbs in her backpack. We are loving it. I sure hope you will make the harness you have in different color pinks, purple and teals. A girl must have options. We love our fat cat backpack.

Best cat back pack ever

We have a Maine coon and this cat backpack was the best decision. Also the harness is very good! Our cat run around with it on 😸

Bob loves it!!

We weren’t sure how Bob (she is a girl) was going to do with it, but she really wants to go outside. I did what the instructions say, sat it down, let her check it out. She would get and sit, and we would give her treats. My son took her for a walk and she Loved it! She gets in and just sits and looks at us. My son tried the bike, but she didn’t like being in his back for this, but she did ok if on front. We will have to work our way up to that. Best cat carrier and worth the money!! Thank you! We may have to get a second for our other cat, but she is just not as adventurous as her sister.
Harness fits perfect as well!

Nike loves it!

My 14 year old loves his backpack. I carry it upfront so he can see where we're going and he loves the luxury of hissing at dogs without their faces in his personal space. It's definitely giving him an ego trip. Thanks!
