This morning, as she often is, Mary Ellen McMahon was walking her dog Jax along Sawmill Brook, which runs along the northern edge of Millennium Park, when she spotted a cat in the marshes. A really big cat. As big as 45-lb. Jax, she reports.
A young bobcat, perhaps? In any case, a good reason to start leashing those chihuahuas and yorkies.
It didn't move while I took photos. I walked away and it started to move. When I peeked back, it saw me and froze again.
