This is why there is no 'Bring Your Cat To Work Day'.

One of my cats does that if you leash him.
Once, my sister insisted on taking him for a walk, and he did walk, but only for a little bit. Then, she had to pick him up because of his "playing dead" at the end of his leash.
She ended up tying him to the dog she was walking, and just let him drag the cat home. He was a Great Dane/Akita mix, so it didn't slow his roll down one bit.
