So my 1yo kitten who's been spayed and has recovered quite well had these stitches and it's 17 days now, they're not taken out cause her vet isn't available yet but when consulted he said it's fine and even if they were never taken out they'd fall out on their own. Today this last stitch seemed to be slipping back in, the one next to it i found gone the other day (not sure whether it's fallen on its own or she pulled it out. This is what it looked like before vs now after it disappeared. It also oozed a bit of what looked like clear pus and the skin seems to be closing after it. Is this possible for stitches to slip back in? Is it dangerous? She is definitely going to her vet as soon as he's available but I'm worried and would appreciate some second opinions.
