Cat Rides in Backpack
Take your cat on a cat carry!

   
Workout with Your Cat
 
Here's another idea for burning calories, losing fat, and building muscle!
I go on nature walk with Kit Casanova riding securely in my backpack.  He loves it and so do I...and if you think packing a 13 pound cat around isn't excercise, well it is!  It's also good for posture, and the abdominal muscles because it's necessary to tighten the abs, keep the shoulders in alignment, and work the thigh muscles!
