Not Again

Otis.
A grand old guy, only not too old. About 7 years old, give or take a year. (Isn't it enough I remember all their names?--the ages change every year, and i have well over 100 pets to keep straight).
Otis now has cancer--the same kind Tucker has. A tumor (or tumors) in his leg. Tucker's got them in both front legs. Otis has it in one leg.
Treatment is to amputate, and then do chemo. That extends his life by about a year. Maybe a year and a half. Without it, the tumor(s) grow, the bones become brittle, the life expectancy is cut down to less than half that.

Let's hope that old saying about things coming in three's does not pertain to this. Cancer is a bad, bad thing.
