I also noticed that there were numerous "scrapes", where the lion had kicked back with his two hind paws and then urinated, in the area of my cameras after the second lion's visit but not after the first one's visit. That strengthened my guess that the second one was a male because they "scrape" far more extensively than females.
Mountain lions can have kittens all year long, and many do have them in the winter. So, it wouldn't be too surprising if a female were in heat now.
After all this big cat activity, I'm trying to be extra aware of my surroundings when I'm out in the woods. Today, a deer watched me and Shyla walk through the forest shortly after sunrise.
It was Shyla who alerted to me to the doe's presence when her nose started sniffing and then she looked intently at the deer. Believe it or not, she didn't even think about chasing the deer.
What a good girl!
