Tocho and Kaya, 2 of 4 sibling mountain lions of the cheyenne mountain zoo, colorado springs.
Tocho was grooming kaya for a good amount of time today, while she continued to groom herself. He seemed to be a little over zealous about grooming her head, and would pull her face back into odd expressions. It was awesome :3
also, i'm officially volunteering there now. Won't be the same as getting to work with these guys in my internships, but at least i'll be around more often taking pictures ^^
