Back Expandable Cat Backpack Carrier, Fit up to 12 lbs, Space Capsule Bubble Window Pet Carrier Backpack for Cat and Small Puppy

This carrier is pretty good. It works well for my ferrets but is a bit small for my cats. My smaller cat fits ok, but my big boy can't move or turn around in it. It's a bit hilarious actually (we only tried it once but we got a good chuckle at his expression). It is definitely better suited to smaller pets. I mainly got it for my ferrets so this wasn't really a problem for me.The only thing I would change is that you have to take the animal out to transform it from backpack to the more open back with more room. This is because the only way to extend it is to unzip the back, lay the back cover down, then zip up the extension. It would be nice if the extension was on the outside so you could extend first then unzip the inner part. You would still have to have it partially open and put your hand in, but I think this way would allow for leaving the pet in the carrier while extending as long as you are careful not to allow the pet to escape. All in all though it's a pretty good carrier.

My cat loves this backpack for transportation and just to play in. The best part is the expandable back - it makes for much more space when we are not moving around. My cat is about 8.5 pounds and can comfortably fit without the back expanded - anything over 10lbs may be too tight of a fit.

Our cat is 7 and she hates car rides and cat carriers, but she loves this backpack. Both in the car and hiking through the woods. She has plenty of room to lie down or sit up. There are a lot of ventilation holes. She was calm and curiously looking through the plastic panel the whole time. No distress in the car either. Love it!

I like it, but only thing i would change is the flooring. Its too hard... i feel like better cushion would make the cat enjoy it more. Recieved lots of compliments on it.

I bought this for our new kitten, Morticia, so we can transport her around in a less traditional way. She loved it from the moment it was unpackaged. I've also used it to take our other adult cat to the vet. She seems to be more comfortable in this than our old carrier. I believe it's because of the increased visibility. Everybody remarks on it! We dropped off the kitten to get spayed at our local outreach last week. Several of the technicians commented on how it is the best cat carrier. It is versatile in the different ways you can carry it. You can carry it by the handle on top, wear it as a backpack, or lay it flat and carry it cradled. I hadn't though of the last way but that is how she was given back to my by the vet and it kept her more comforted with less jostling. I catch her climbing into it often.

Bought this for my newest kitten I adopted from a hording situation at work. I work in Veterinary Medicine and I absolutely love this carrier. My little one was spayed and she's got so much energy and having the back part open up has been a lifesaver keeping her from running and jumping. She sleeps so well in it and loves to go on adventures on my back. I've gotten a lot of compliments and questions on where I got this bag. 10 out of 10 recommend

She like to get inside and play. It's study and supports her well when we're walking and its actually big enough for her.

This little boy of mine loves it the most and he loves being my riding buddy. He feels safe in it but sometimes he rides in the actual car without the carrier.
