Lyrics (sounds just like guitar)
meow part

I am just a kitten, hardly fit my mittens
Much too small I figure, one day I'll be bigger
One day, I'll be, a great big kitty cat use
Open, windows to go from flat to flat

Meow part

I am just a kitten, hardly fit my mittens
Much too small I figure, one day I'll be bigger
One day, I'll be, all grown up and strong but
Till then, I'll just purr and sing along, and go
