Give Candi a kiss for me! i, too, have two white kitties, Venus and Daisy.
Venus was spayed the day before i picked her up. She had pink strings on her spayed area, and i was very careful not to touch her there, so as not to hurt her.
In their kitty bin is a small scissor with round ends that i bought from a Japanese store. It is supposedly a human nose hair scissor, but i use it for my kitties, as it will not hurt the skin when the ends are touched.
About two weeks after, i could tell the skin area where the spaying was done was pretty much closed up, and the strings were starting to stray. So, i gently snip off the strings, one by one, very slowly and carefully.
Could you do the same, i wonder? If not, i concur with the rest, the vet should lend a helping hand to snip off the strings since they are not dissolved yet. It sounds uncomfortable for Candi. (?)
