So...it's been a bit over three years and the cat my wife has named Fraidy still shows up just about every night seeking food. We still feed her. Her behavior has not changed a bit. Last month we went to Miami for a week to visit relatives and our neighbor fed Fraidy. When we got home, his wife told us, "Wow, we thought you were exaggerating, but that is one seriously Fraidy Cat!"
So late last week, I want to say Thursday, I was slow bringing in the cat food bowl. Went outside to cover the grill and I could have sworn I saw TWO cats running away, one to the right and one to the left. I covered the grill and came back in and left the cat food out in case the cat came back. A little while later, sure enough, a different cat from Fraidy came to eat.
This one showed up again last night and tonight and I'm convinced it's either someone's outdoor cat, a new stray, or an abandoned cat because tonight I was able to go outside and walk right up to it and let it, scratch its head, etc., and it meowed happily (whereas in over three years, Fraidy Cat has never made a single sound). No collar. I guess the thing to do is to e-mail the neighborhood to ask if this is someone's cat and maybe to post some flyers. Seems like a very nice cat and it's certainly a beautiful animal, but I'm not sure we would be good at caring for a cat if we got it to come inside. I know it doesn't belong to anyone in our row of five townhouses.
