Cat In A Backpack is very nice product. We are car-free, so getting the cats to the vet was a bit of a challenge. While our transit system does allow carriers on the bus, I’d rather not take an animal on transit if I can avoid it, and walking with a cat/traditional carrier a couple miles is harder that you might think. My traditional carrier is too big to bungee to my rear bike rack, and I don’t have a trailer.
I bought this thinking I’d probably have to return it, but it works really well! I was so surprised. One of my cats asked for rides in it now. The other two don’t like it, but it still gets the job done. With a large male adult cat, the weight on the shoulder straps starts to pinch shoulder nerves. I’m a 5’9” active female, so I’d prefer hip-weight distribution, but for a 10 minute bike ride, it’s fine.
For the kitten, I didn’t even notice her after an hour. So, short trips or lightweight cats? Your gold. Much more than that, you might prefer a trailer.
