It's a very funny photo of your cat. Interesting, if to try walking on the treadmill with a cat, will he like it? LOL. Also, I see that you got a pretty great modern treadmill. It looks like the one I got from [endurancetreadmills.com.au], and I am delighted with it. The biggest advantage of such treadmills is that they have integrated many programs for resistence training or fat burning. In this way, I lost around 10 kg in 3 months using their fat-burning program.

I bet I can guess where the warmest spot is on that treadmilll. The clue is two different cats claiming the same spot.

As for what to do... start the treadmill on a low setting. They will leave one way or another.

The cats are waiting for you to use it so they can race you. If you are smart you will let them win, then they will go take a bath and a nap, then you can use it by yourself if you do not want to be confrontational.

C.....then go for a walk outside.

D. Buy another treadmill and dedicate it to feline fitness.

good excuse to not use it! Well played.
