A slim McMug

McMug had lost some weight recently, so he's actually more tone up. Actually I'm quite worried about the lost in weight, worried that he might be sick or something. But he is still as energetic and eats well.
So I come up with some possible reasons for his weight lost.
As it had been raining quite alot recently, a lot of dog owners didn't bring their dogs out for walk. So McMug didn't get to eat the food that other dog owners brought during his nightly walk.
And since there aren't many dogs to play with, McMug began playing a lot of his cat friend. And their form of play is CHASING! Yup, McMug will run a big round around the cat, then the cat will suddenly pounce on McMug or chase him for a short distance. And this will go on for a while.
And thus McMug lose his weight! Wahhh... how nice it will be if I'm the one losing weight!!!!!!
