Clio should probably be about 8 lbs. It takes her belly a little longer to roll over than the rest of her! She was a street cat and you have to make her stop eating.
Oswald the wonder cat is at his prime weight at 17.5 lbs. He can look over my coffee table.
I can't imagine if Belle weighed any more. It is hard enough to keep her in Fancy Feast as it is. She packs it in and never gains an ounce. Me? I look at a can of Fancy Faast and it goes straight to be thighs! LOL!
