“The Fat Cat" cat backpack is our international best-seller! It holds the most weight on the market — up to 25 lbs of cat!

Our breathable cat backpack is great for larger "big boned" cats, 2 medium sized cats (yes, you can use it for two cats), or lots of kittens!

All of our styles have a clip and bungee for you to attach a leash so your cat can "hang out" of the backpack!

This is our second one and my travel cats love them

Two out of our five cats love to travel with me. Our main coon was the first one to have this backpack and I found it to be very spacious and comfortable for her. We decided to purchase a second one for the other travel cat and she seems to like it just as much

Even my hater cat likes it

Other than food, my cat likes one thing and it is a shoelace with a hair tie attached to it. I got this carrier because he gets so upset every time we go to the vet that he can barely be examined (even w/medication), I hoped getting a new carrier and attaching different feelings to it would help. I wear it in the front so that I can pet him while we walk around. I leave the top just a little open so that he can stick his head out. (Otherwise he jumps onto my shoulder, even tho he is attached to the carrier). He won’t admit it, but after three walks outside, he is starting to like it. It’s very sturdy and well made. Happy with my purchase.. which almost never happens with cat products.

Great for my boy!

I've had the backpack now for a couple months, and so far it has beena great fit! I bought this for my 12lbs cat Nimbus because other backpacks I had bought seemed to collapse under his weight, causing him to have less space. This design has help up really well, giving him plenty of room. I rarely use the bubble or screen option, since Nimbus is content to ride along and doesn't jump out. this allows him to stick his head out the hole on the side as well as look out over my shoulder. I haven't tried the bubble yet, but the screen has been fairly easy to put back on as needed. Though sometimes it takes a couple tries for it to thread correctly so that it screws on. I do not use the bungee clip in the bag because it is too tight and doesn't allow him to lay down. Instead, I keep his leash hooked to his harness. At first, the backpack was too stiff and was uncomfortable on my back. But after about a month of wearing, it broke in a bit (making it much more comfortable). After ordering, it took about a week or so to arrive. Overall, Nimbus and I are thrilled with it and would definitely recommend!

Excellent for larger cats

I've been looking for a bag that wouldn't be too small for my big guy who's 25lbs Maine Coon x Ragdoll. Ordered this bag and it came so fast. Really well made, it took him a couple tries to get used to it, now he loves it. I put a blanket in the bottom of my bag and props him up enough to look around. Highly recommend.

Brady loves it!!

My cat hates carriers or being put in anything, but with this backpack it’s something about it he likes, he will sleep in there and randomly go in there.. it’s crazy but he just loves it, I’m so glad I bought this!
