Luna (in my avatar) was only a few months old when her time came. She had what I thought was a routine abscess, so I drained it myself, and a few days later she had passed suddenly in the night with no other symptoms. I have been advised that it may have been the location, or that the abscess was in fact a mammary tumor that abscessed. I should have taken her in for a check but I thought I knew what I was doing. My sweet girl, I promise I will learn from this! Better safe than sorry. You were a special girl, a very timid and loving and gentle creature. We miss you.
