Sygma and Java when they were both around 4 months old.
This is Yuugo (right), my stepdaughters kitteh, and my kitteh Lucy (left). They're a month a part but have been best friends since day one. Lucy loves to clean Yuugo and make sure he looks proper. Yuugo loves to do the same to Lucy...for about 10 seconds then he grabs her face and bites her ears :P
