Skin tumors are less common in cats; and although most cats are vulnerable, white cats are especially prone to this type of tumor. Skin tumors manifests as a visible lump on the skin, mostly affecting vision, smell, or eating.[1] Benign tumors take several years to develop and are more difficult to detect due to their freely movable nature.[2] The only indicator of benign tumors is self-trauma of a form called lick granuloma or "boredom sores",[3] which can be caused by excessive licking by the cat.[6] This is a sign that the cat is suffering from anxiety.[4][5]
