spayed kitties... infection?

I have two 8 month old kitties that I had spayed 3 days ago. One crawled under my bed and just came out yesterday and the other acted fine immediately. She was jumping and playing even though I tried to prevent this. She also has licked herself a lot. I had to work on post op day one and she must have licked herself all day. Her incision site looked flaky and has dried skin around it, a bit crusty. Today when I checked, it is still flaky and now swollen, but no discharge and not very red. Almost looks like a stitch came out, but not sure. The other cat who relaxed for 2 days has a site that I can barely see and looks great. Is my kitty in need of antibiotics? Is is safe to put antibiotic cream on at home? I work at the hospital and one of my nurse coworkers suggested I bring home steri strips to hold the site together. Is this safe? Any suggestions are appreciated!

IMO I would have the Vet clinic have a look at it, it could be infection and in need of an antibiotic, hard to say with out seeing....and there are times the stitches themselves become irritated and infected and need to be taken out early. this SHOULD BE DONE AT NOT ADDED COST TO YOU...so its best to have it looked at..besides sterti strips could easily be licked off and swallowed.  -)
