Congratulations to Sweet Pattootie! He's making a big lifestyle improvement and it sounds like it is for all the right reasons, so (hopefully) he will be able to sustain it. We found that we had more energy after we bought "The Cloud," our good quality mattress with the memory foam topper. Better sleep leads to a better life!
My cat, Bootsie, weighs in at 13-14 pounds. She's a Chubster, too. I know it's not good for her health to be so overweight. She has arthritis and it's hard for her to get around. The weight is hard on her heart, too. But DH says, "let her be." She and Midnight will turn 17 on 1/15/2011. DH says Bootsie will never lose enough weight to make a difference, so let her enjoy the one thing she can - her dinner. As long as she doesn't gain any more weight, I'll go along with it. She gives me those big "puppy dog" eyes; The ones that say, "I'm STARVING! I can't remember the last time I ate."
