My cat loves it. Sleeps in it when we're at home!

My cat loves it

My 18lb cat Charlie loves it! I trained him first to like being in the bag. And it involves lots of treats and praises

Love it!

This is a great backpack for my Maine coon. The ventilation is good and I like how structured the bag is. It doesn’t collapse under my heavy cat! When out at the park, the backpack also doubles as a nice hiding spot.

Great, my cat has already put over 50 miles in this in the past couple weeks.

He loves it, loves riding on top of it. It works great when I bike and take him, although I make sure the top is zipped.
I recommend it.


shadow is still getting used to it, but it is easy to put him in. when I first got it , I put it on the floor and the other cat crawled in it to sleep. all in all, love it.
