2nd Generation Rat Poisons* Linked to Deerhorn Bobcat Deaths --
–by Kim Hamilton
Last year DeerhornValley.net published some photos of what we could only identify as a "mystery cat." (See top photo at right) It now appears that a deadly outbreak of a lethal mange has made its way to our area, and research is pointing to the use of anticoagulant (blood thinning) rodent poisons as the cause.
These poisons (D-Con, Tomcat) require multiple feedings to take effect, but as the squirrel, rat or gopher becomes sicker and slower, they also become easier prey for bobcats, coyotes, mountain lions, and domestic dogs and cats.
In the Santa Monica Mountains more than half of the bobcat population has been wiped out by this mange during the last 8 years. All victims had ingested anti-coagulant poison.
Once a bobcat becomes sick, its behavior changes. They become less interested in food (or less able to eat), more readily approach residences and water sources.
These recommendations are from the UCLA research group currently investigating the deadly mange outbreak.
