Please help!

My kitten was spayed Friday and she is chewing at her stitches. I can see a hole at her incision. I of course know she needs to go to vet at first thing, but my question is how do I keep her from gnawing and making it open more? I'm terrified she could open herself up fully and die. Someone please tell me what I can do! I'm panicking!

Get an old men's tube sock and cut the top off.  Put the tube part around her mid-section, covering the incision. 
 

Thank you! I think it's safe that I'm in full blown panic mode and won't sleep much!!!
