I picked them up Thursday evening after work. Smudge's tail is healed. However, I had the vet perform a couple of additional procedures since he was being boarded anyway. He had some stitches taken on his left eyelids, so he'll be wearing the collar for another week. Now the fur won't rub and irritate his eye any more. He also had his teeth cleaned.
Ghost was just along for boarding, although they did tell me she'd need a chip installed due to city ordinance. Why they didn't tell me on the front end? I could have had it taken care of then. Oh well. It's not difficult or expensive, so I'll take her back in the next week or so.
The kitties are happy to be back and enjoying their home! Hopefully, they didn't mind the boarding too much.
