The last cat I saw have kittens (victim of dumping) meowed VERY loudly when they were coming out. Especially the first, which was stuck the way you're describing. She was very young and just a really narrow cat and is to this day. The scary part was, she had FIVE and afterwards she had bright red blood trickling (faster than a fast drip) from her ladyparts. She turned out OK and so did all kitties. I had a heck of a time rehoming 5, let me tell you.
Sometimes I think everyone should have a pet, then I see how many people should really never, ever be allowed to be responsible for another living thing's welfare.
Sounds like their all going to be OK to me.
