Timothy Kooyman was ordered to trial in May on four felony animal cruelty charges. Last week, San Bernardino County prosecutors amended the charges to include using scissors as a deadly weapon.
Kooyman has pleaded not guilty by reason of insanity. If convicted, he faces up to seven years in prison. It was not known if he had a lawyer.
Prosecutors say the 25-year-old Kooyman lured stray cats, then broke their legs and cut off their tails with scissors. Last May, Kooyman allegedly set a live cat ablaze and started a brush blaze.
