Miss Teia was definitely too big for her frame. It took us about a year to socialize her and another 2 to teach her how to play.
Careful feeding and increased activity got her down to 16 pounds, which was much better for her.
Teia really blossomed when we moved here. She was 15 at the time. She learned that Outside was not as scary as when she was a street cat.
The ones of our who do (did) like Grass Time, was always in a fenced yard, with human chaperone.
She liked taking naps in the sun. This was shortly before her 17th birthday.
