A 21-year-old woman from Boulder is currently in police custody for having allegedly blown heroin smoke on her boyfriend's cat, Muffin, until it succumbed to a massive overdose.

Danielle Blankenship, the smack-blower in question, absolutely denies she would ever smoke heroin or do anything to harm Muffin. But when police arrived at her home to investigate a domestic violence complaint, they found Muffin, lying paralyzed at the bottom of the stairs.

Blankenship's boyfriend told them he'd called in the complaint (she'd struck him "because he wouldn't let her use his phone"), and that he'd witnessed her blowing "heroin smoke in the cat's face." The still-breathing cat was then brought to a veterinary hospital to be treated for poisoning.

"They gave it some IVs, and the cat rallied at one point," says Boulder Police Spokeswoman Kim Kobel. "They thought it was going to make it, but then it crashed soon after that and it died about 6:30 last night."

Sad. Toxicology tests are being performed on Muffin today, with results due next week. If heroin was indeed in his system, Blankenship would face misdemeanor animal cruelty charges, and possibly felony charges. [9news.com, KDVR, screengrab via 9 News)
