Look!  I think my cats might be friends. 

When Violet and Hobbes met, they were not happy with each other.  Violet arched her back and hissed.  Hobbes ran away, terrified of the tiny white monster we had brought him. 

Now they are sharing their space on top of the microwave.  I love it. 

Funny how cats can learn to love their enemies in a matter of months.
