I have never seen a more universally-adored cat toy than Zanies.  Every cat I know absolutely LOVES these brightly colored mice.  I have to keep a supply of these furry mice on hand for my cat.  I dole them out to her.  She usually gets the tail off shortly after I give her a new one, and then walks around with the tailless mouse in her mouth.  She drops the mouse into her food dish (dry food) so she can eat, and then collects it again when she's done.  These are a little larger than the black/ white/ grey versions.  My friend and my sister both give these mice to their cats as well, and they are also their favorite toys.  I often wake up with one of these mice in my bed.  Every week or so, I pull out the stove and the sofa to collect mice.  They go back in the drawer for rotation when the cat loses her mouse of the day. EDITED....... Although my cat still loves these mice, I have to say that there is something different about the latest box I purchased.  The mice do not hold up as well to play anymore.  The body is now made of some kind of black plastic that crushes pretty easily, and the fur separates more quickly.
