A friend of mine just went through this with his 16 year old cat. Brief periods of chemo pills, but it stopped eating.. and that was the clear sign that it was time. Do the right thing, and don't let the poor thing suffer. I have had to have 3 of my dogs put down over the years... very hard to do.. so I sympathize. Focus on the good in its life that you gave it instead of the sudden loss..
