This a reply to Smithduke. A lot of people may not go that extra mile in treating their cat with cancer, not because they don't want to, it's because they don't have the financial means to do it. Our cat has a large tumor in her mouth. Treatment is out of the question because we don't have the money. Plus having her go through all that would just make her more miserable. For now were going to keep her comfortable as long as we can till its time to put her to sleep.
