Yeah bobcats have a vastly different appearance than mountain lions. People get excited when they see movement of something larger than normal and tend to have trouble interpreting what they see. I feel like the black panther /mountain lion thing is some Granby folklore. I’m not familiar with the video from Colorado you are talking about, anybody that’s so freaked out by an animal in their yard in Colorado is probably not going to be able to reliably identify it. When I used Nextdoor in our neighborhood their would regularly be phots of a mangy fox that people were freaked by, it happened to be the same one that built a den under my barn… It’s interesting here, I live close by to Granby in North Canton. I have had the opportunity to observe more animals here than anywhere I have lived. Had a family of foxes last summer and the local bobcat appears to be pregnant, but those guys will be impossible to see.
