Specifically, bobcats in California, Oregon, Washington, and British Columbia tend to be larger than those in other parts of their range.
This is likely due to a combination of factors, including:
* Abundant prey: These areas have ample prey like deer, rabbits, and rodents, which allows bobcats to grow larger.
* Climate: Cooler temperatures in these regions may also contribute to larger body size.
* Genetics: It's possible that populations in these areas have evolved with larger genes.
It's important to note that there is a lot of variation in bobcat size even within these regions. While they may be the largest on average, you can still find smaller bobcats in these areas and larger bobcats in other regions.
