@porters, your cat reminds me so much of my cat, Angel. She does the same thing. (And she is also a tabby.) She is outside a lot during the summer and goes a little nutty when it's cold and snowy outside in the winter, and sometimes goes out anyway. If it's a pleasant day she might sit in the sun for a while, but if the temperature is well below freezing she comes right back in.

Did you ever find out where your cat came from? He must have abandoned another home, or maybe he was abandoned. I'm glad he has a nice home with you!

p.s. I found this post in the PHC Caturday space and upvoted before I realized it's two weeks old. :-) So then I decided to go ahead and comment anyway. I love your bird photos! Wow.
