This catamount was killed on a highway here in CT just about a year ago.
It's hard to dispute their presence when you have proof like that
On the other hand, last month I thought I saw one where we were camped.
It was nearly dark and it just happened to cross my field of vision. This animal was the right size and shape and that's all I could really tell but "that's a mountain lion !" popped right into my head
The next morning I went and tracked it and found fresh tracks.
It was then obvious that I was mistaken. This was only a bear. A small skinny bear, but not the lion that I was worried about
