THey've messed it up a bit now andit's notrunning so well, they loved the smel of the inside as it had a dog treat in it, they also seemed to love riding in it. I have a tank and they are always pushing that around but never seem to get a good enough photo. I dropped a perminant marker pen to write DO NOT ENTER on the kitchen door, well the pups pinched it and before I could get it back they had written all over the fllor, not sure what it says???
