My son found two kittens in a junk pile at an abandoned house. One was a pretty little tortoise shell and the other a pathetic tiny short haired gray kitten with a broken stub of a tale, legs like toothpicks that didn't look like they could possible hold up the body. Her belly was big like a famine victim and she had this big old head on her body. Her eyes were matted and she was the ugliest thing I'd seen. I bottle fed her kitten formula and she survived somehow. Now the name just sort of developed over time. The big head made her look like a bear, a little bear. It stuck. She is still a small cat and beautiful. She has my cat hating husband eating out of her hand. On a side note the tortie was adopted and Tillie lives a very good life also.
