welcome to another Angel!
hi tammyangel!
we have an 11 year old (11 in June actually) named Angel, too! hurray! we adopted her a little over 2 months ago and her history was that she was extremely overweight herself when she was first surrendered to the shelter. that was 2 1/2 years ago. she was over 16 lbs when she came in and they got her down to @9 lbs in i think about a year or a year and a half. i think she is currently still @9 lbs. really hard to imagine her at 16! we're also planning on adopting another kitty who, believe it or not, was 27 lbs when she was surrendered, but is now down to @15. thank goodness. good luck with getting your Angel's weight down yourself. it just has to be a very slow process so you don't shock her system.
hope you post some pictures. we'd love to see another Angel!
