*EXLODES*
Kitten huffing is a popular, though controversial, alternative to street drugs such as skag and crank. Despite a long-established tradition of kitten huffing in western nations, the daily practice remains subject to a widely-recognized taboo. It is believed that experiencing kittens can result in undesirable side effects and kitten-related human fatalities, and even unapologeticly frequent huffers caution against using more than two or three kittens per day. Also causes mild ear aches as well as violent diarrhea, and rare cases of fleas and heart worms. If any/all occur consult a veternarian.
The huffing technique dominant amongst casual users is the 'cupped hands approach', developed by the Marquess of Queensbury as a remedy for the pain of head injuries sustained while boxing.
One should refrain from the use of rolled up dollar bills, as the kittens tend to clog.
