Cat Toy Made Of Felt And Wool

A cat toy I have made for Felecity for my Newbie vs Vet swap (as a vet).
I only used grey velt and black and white wool. I knitted two strings, one white and one black.
I sewed this to the back of the mouse when it was almost finished.
At the end of the tail is a little bell attached.
In the filling of the mouse I added some plastics so it will make a cracking sound, just what a cat likes.
