My cats...

The family wouldn't be quite complete without Blueberry (the grey one) and Eliott (the red-haired one) more commonly known as Bob or Bobby.
Just like with humans, there are as many personalities as there are cats.
In summary, I could say that Blueberry is as sulky, smart, and quiet as Eliott is cool, not very clever, and a smooth talker (just like in humans)!
