B-337, or Bobcat 337, is released after being captured by National Park Service researchers on the western end of the Santa Monica Mountains. This female bobcat has three legs but it does not appear to be hindering her ability to care for herself and at least one kitten.

It started as many things do for our researchers. One of the many camera traps set up throughout the mountains caught an animal passing by. But one bobcat on the western end of the range that kept making appearances was especially interesting: it was tripedal, or three-legged!

Eventually, she landed in one of our cage traps, allowing biologists to take a closer look. It's not clear whether the missing leg is a birth defect or an early-life injury. But B-337, as she's called, doesn't seem to let it get in her way, as the above video shows.
"Bobcats catch live prey, so that means she's managing to hunt with one front leg--and doing it well enough to feed herself and her kitten," says biologist Joanne Moriarty.
That kitten, coincidentally, ended up in one of our cages a few days prior to his mother. While he, identified as B-336, doesn't have a missing leg, he is missing one of his ears. Again, Moriarty is unsure why.

Despite these deformities on top of the usual challenges that wildlife face in the Santa Monica Mountains (roads, rat poison, being eaten by other animals, etc), they appear to be surviving just fine. The only notable difference between these two and other area bobcats is their home range. "It appears to be on the smaller end of normal for a female bobcat," she noted. "Based on our long term study of local bobcats since 1996, females average a range of two to three square kilometers [or .75 to 1.15 square miles]. I'm not seeing it that big with the preliminary data gathered so far."
With a collar now tracking B-337 and blood samples of her and the kitten being analyzed, Moriarty hopes to learn more. When she does, we'll report back here.
