The dog is hungry most of the time, but he doesn't always want to eat his dog food when it's served. He always hopes to get a little bite of human food, either accidentally or on purpose.
At various times of the day, when he really needs some that especially has fiber, he finds a Kleenex or several Kleenexes and has a little snack.
The other night I was sitting on the couch with a small blanket over my legs and lap. He got under the tent and was very quiet. I thought he was just enjoying the warmth and security. I was WRONG. He was eating a Kleenex.
The moral: Where there's a will, there's a way. OR Fiber is where you find it. OR If your master doesn't feed you properly, go scrounge for yourself. OR If you keep your yap shut, no one may see that you've done wrong.
