I've been that guy before - walking through neighborhoods rattling a kitty dish and call her name.
Only cat lovers would understand, (everyone else must have thought I was quite mad).
LOL! That might have been me too a couple years ago. I had a guy over to clean out my air ducts and had to leave door to the garage open for his aparatus. Normally my cat hides under the bed but when the guy went in their with his air hose, I saw my cat fly out of there. When the guy left, I searched the entire house and couldn't find the cat.
So I started walking around the small neighborhood for an hour rattling her food dish like a fool. No luck. So, I went out on the back deck and continued to call her. Finally I gave up and turned around to go back inside and there she was, standing on the other side of the screen door looking out at the fool on the back deck calling her name.
Evidently she found another secret hiding spot in the house where I couldn't find her.......LOL!
