Quite new to internet shopping so a tad disappointed with this mouse. I put it in the cage after the old one had died but the children were not impressed. Ok - it's cheaper to feed than the last one but it doesn't scurry around the cage or bob in and out of the sawdust or even look that cute. ONLY JOKING!!! Yes its a great bit of kit. I bought it to go with my DELL laptop and it's a real asset. Very comfortable to use and very easy to set up. No complains at all. Will buy the wireless keyboard next.
