This doesn't look good at all. We had our kitty spade two weeks ago and her stitches dissolved on there own in about 10 days. You can't hardly see a scar at all. These stitches look opened and infected in your photo. I would get her checked out to be safe. After the surgery they gave me pain...
My daughter usually holds Kitty Kitty on her lap and in kitty's favorite blanky. She pets her and keeps her calm until we arrive to wherever we're going.
We've never had a problem. Hope this helps.
