The Meaning of Pudgebutters

I hate to admit that blogging on a regular basis isn't as manageable as I had hoped.  I set up this blog with good intentions & then had a couple of bad weeks at work which resulted in no desire to sit in front of the computer once I got home.  However, that hasn't slowed me down on Twitter too much.  That brings me to this post - I've received some tweets asking what is a pudgebutters.  It's so simple to explain.  It's a nickname for my plump kitties!  It's just a word that I made up one day & I'm not even sure how it popped into my head but it did and sounded funny so I kept it. So there you go - the meaning of pudgebutters.  What are some funny made up names you've had for your pets?
