I had to deliver two kittens once, too. I had a foster who was pregnant. She only had two kittens, which meant they were large and therefore couldn't turn around, so they came out "feet first", too. We had to pull Yankee out, but Doodle (they were born on Independence Day) managed to come out on her own. I remember panicking, too, especially since it was a holiday, but the vets at the emergency clinic were very helpful. Neither of those kittens were "tetched", though, in fact they were both very smart little girls.
