"Let's just say I would never wish what I'm feeling on any living soul."

While most of her followers promised to search for the cat, one fan questioned the huge reward and Cobain immediately went on the attack.

"Really? You can buy like ten black cats for five bucks. Does yours have diamonds up it's butt?" one follower wrote.

To which Cobain responded, "No diamonds, she just has my heart. U can buy cats but you can't buy love. And you can't buy a sh**ty personality. Clearly."

Cobain has had a bad track record with cats, previously accusing her estranged mother Courtney Love of killing not just one of her cats, but also her dog!

In court papers filed by Cobain in 2009 seeking a restraining order against the troubled rocker, Cobain claimed her 47-year-old mom's reckless behavior lead to the early demise of her pets.

According to the documents, the cat died after getting caught in Love's messy piles of "Etsy fabrics, boxes of paperwork, trash and other possessions," and the dog overdosed after swallowed prescription pills from Love's drug stash.
