Many of you who submitted your stories agreed to share them with media outlets to warn other pet owners. Thank you for your courage in speaking out.
Because veterinarians are not required to report adverse reactions, every story matters.
IMPORTANT DISCLOSURE: NO ACTIVE LAWSUIT
This site was originally established to collect cases for a potential class action lawsuit. The attorneys who initiated this effort did not follow through.
However, your data still matters. We continue collecting adverse event reports to:
Document the full scope of Zorbium®’s impact
Support ongoing research into safety concerns
Provide data to any future legal efforts
Help other pet owners make informed decisions
If you are an attorney interested in pursuing legal action, all collected data is available.
BREAKING RESEARCH: Black Cat Correlation
Analysis of over 100 submissions revealed a critical pattern: adverse reactions to Zorbium® correlate strongly with coat color. Black cats and black-and-white cats show disproportionately higher rates of severe adverse events and deaths.
We are actively reaching out to veterinary schools and researchers to investigate this correlation.

IN MEMORY
“The least I can do is speak out for those who cannot speak for themselves.” — Jane Goodall
This work is dedicated my Spooky Tooth and to all the cats lost to Zorbium®, and to the pet owners who refuse to let their deaths be in vain.
