I walk my dog each night, between eleven and midnight, along the alley that’s about 200 feet above the boulevard, and runs from the library to Morton Street. On Saturday, Oct. 20, around 8 p. m. , a cougar, weighing maybe 180 pounds, walked by my house in the alley. When car lights came up behind the cat, it veered left between houses towards the boulevard. Cougars are stealth animals; if you see one, there are more. And why the alley?
