Wait until they have their own cat that has stitches and they will see how hard it is! Samantha started pulling on her immediately and I know it had to hurt like the dickens the way she was pulling on them but she didn't care. I think she did manage to get a couple of them out before they were due to come out but I took the rest out when it was time myself. No need to take them back in for something that simple when everything looks great.
