Cuddle parties are intended for people who are emotionally sound. People in therapy or who are seeing a mental health professional are asked to consult their doctor before signing up for a party and to tell organizers of their situation.
I can see the point, the need for this in a big anonymous burg like New York. Still, I find the cow part a bit odd - and disturbing:
An introduction to cuddling ensues, first by hugging three people. People then get in a circle on their hands and knees, rub shoulders and moo like cows. After a bit of swaying, everyone falls to their side, which puts them into an easy cuddling position.
Just weird, man.
