Meet Pebby, my fat cat. Just like many of us, she loves her food and has a major weight problem. She is now 9 years old but we adopted her when she was less than a year old. She weighed 10 pounds then and gradually bulked up to almost 18 pounds! The only thing that worked was to give her a starch blocker pill before each meal -- these came from her vet but are no longer available. With those, she was able to gradually get back down to 12 pounds. At her last checkup she was back up to 13 pounds and we put her on a new cat food that was like the Atkins diet for cats -- really low carbs. I took her in for a weight check this week and she had GAINED two pounds. So back to her old food until we decide a better route for her to go.
If anyone has any ideas, I'd love to hear them. She does not eat any other food during the day and only gets a scant half cup of food for the entire day. She really goes out so I know she is not sneaking food elsewhere. And my other cats clean up their own plates without her help.
I am thinking of making my own food to see if that helps.
