Cats on the Greenway?

I saw a couple cats today biking on the Greenway and was wondering if this was relatively normal, or if they may be lost. The tabby had a collar with no name, was very friendly, was hanging out about a block east of the 35W greenway entrance. The fluffy grey was more skittish, and seemed interested in hunting. This cat was on the Greenway near 13th. submitted by [comments]
