Sew normally. There is no smell. But you will never put a cat in there alone!!!! And if you are very lucky and put a cat in this garbage, then definitely not hang it! Hooks suck! They are very slightly bent, hit a little and they fall. Couldn't make any carbines ???? Very, very uncomfortable to use! And I advise you to first come up with where you will hang the cat, and then order this "miracle"!
