Sandie, George IS a grey and white kitty - so maybe there was a patch of white hair there.

I'll let you know.

thanks!

ETA: Is it this?
Mycetoma are tumor-like masses caused by several species of fungi that enter the body through wounds. The typical appearance is a lump beneath the skin with an open tract to the surface draining a granular material. The color of the granules is white, yellow or black, depending on the type of fungus involved. The condition may resemble a chronic abscess that refuses to heal with antibiotics. Some species of mycetoma can cause a fatal infection.

Recommended Treatment: Antifungal drugs are seldom effective. Complete surgical removal is the treatment of choice.
