Impossible to get a cat into it
This is completely useless to me because I can't get my cat inside the bag for long enough to be able to close it. I have been able to get the cat inside using treats, but often there is a tail or even a leg sticking out. The time it takes to close the flap with the zip is a lot longer than the time it takes for the cat to jump out. It is a nice idea having a bag with a shoulder strap for carrying a cat, but a cat carrying solution needs to also be a trap, and this is not.
