This is a total copycat of Don't F*@& With Cats. That kid did the same stuff and ended up killing someone before they caught him. If you haven't seen that documentary, do yourself a favor and don't watch it.
Pull off all her nails with pliers. Fill a kiddy pool with 364 dimes and 2 inches of rubbing alcohol. Tell her for every dime she can remove, she gets a week off the sentence. Don't actually follow through on the deal.
Before any PETA members get worked up, if true, this is horrible and likely indicative of psychopathy. My point is that we if we, as a society, tolerate abortion, which is infinitely worse than this, we cannot clutch our pearls at animal cruelty.
