Hi to all. I've been a loyal COTD reader for years but I'm new to Pet Talk. My cat Trouble was COTD on Dec 7, 2002.

Anyone know much about mast tumors? My 12 year old cat (Spider) has two small growths on his head (one on his ear). The vet did a needle biopsy and saw some mast cells. She tells me that it doesn't look like a mast tumor though. She gave him cortizone in the site. He's going back for a follow up tomorrow.
If they don't clear up by then, she will do sugery and will have to remove some ear cartilage.

Any info would be greatly appreciated.
