is this your cat?

Very friendly, grey with blue eyes. She's been hanging around Walton Ave.

Note the collar.

Nobody? She's definitely a recently escaped stray -- too friendly to be anything else. Plus the collar. No "tipped" ears either.

Yep. She's a family pet. Have you talked to any local vets, put up any flyers? Or, for that matter, checked to see if you have any neighbors whose cat might have escaped. She seems to have a lot to say, by that first photo! LOL.

She could be a neighbor's indoor/outdoor cat.
