This is my mouse
    Lives at my house
Sleeps in a cage
Lives on a shelf

Such a sweet mousey she is
    So forgiving
    Forever humble
I have a bashful mouse
    In side

Ignore the mouse and
    It will chew a hole to break free
Forgive the mouse, the hole will
    Still be there
Mousey just wants to run free
    It is a cute pet mouse
Domesticated from nature
    The instincts never die
For they live inside
Stand aside
There is a mouse
Coming through

I'd say you got a cute mousey too ;)
