The big surprise

I thought it was a cat a rat even a bat,

Maybe a parrot but it wouldn’t like carrots,

Then a rabbit but I wouldn’t have it ,

Of course a hog a bog but most defiantly a dog,

but what should I call her ?Holly? Polly? I’ve got it Molly ,She’s black and white she’s my little teddy bear , And she’s always ready at 12 o’clock for her walk.
