I am so sorry about Shadow and the diagnosis of oral SCC, unfortunately the prognosis for cats with oral SCC is poor and most cats will have survival times ranging from 3-6 months. Cats with small tumors located on the lower jaw (mandible) that are treated with surgery have a better chance of surviving for one year.
