Cat and Mouse

Dear Teemings:
Well, again my cat bumped my mouse off the table, for fun I think. But this time it was my optical mouse. I’ve been able to fix my other mouses but can’t seem to adjust (repair) my cordless optical mouse. I took it apart but apparently nothing’s wrong, but obviously there is. It don’t work no more.
Is it fixable? By that I mean is there anything I can mechanicaly do to this misbehaving (optical) mouse? Is it fixable or should I give it back to my kitttie?

Lost in mouse land, Jake
BTW it’s still flashing at me… Wait! I think it moved!
I think I’ll go to bed now… Here Kitty Kitty. Kit…
