Cats are... special.

I used to have four cats as a kid, and thankfully only one of our cats was this persistent. The other three only wanted to be around you if you had food or treats for them.

Now, just to clarify: My dog Shadow is just as persistent when he needs to go outside or it's getting close to dinnertime, but he is too big to crawl around on me! Although, sometimes that doesn't stop him...LOL!
