There were two little rodents. One was a fancy blue rat. The other was a dumbo blue rat. The rats would gang up on the cats and drive them on top of the furniture by nipping at their back legs. We never left them unsupervised of course. However, on those rare occasions that the rats would escape, the cats would direct us to where the rats were hiding and the rats would gladly come out of hiding toallow themselves to be put back in their cage. Neat relationship. In this photo Captain Morgan and "Little Rat" were sharing some catnip.

Yes. Very nice when people are watching :)
