Our 8 year-old spayed female cat had a unilateral mastectomy this past October to remove a single cancerous growth and hopefully prevent reoccurance. Her cancer has not only come back, it has exploded with growths in her nodes, hips, back, shoulders, legs, chest--pretty much everywhere. Her appetite has diminished, but not ceased, and she still has a full range of movement and enjoys being petted. While we want to keep her with us as long as possible, above all, we don't want her to suffer. Are there any less-than-obvious signs we should be looking for to know it's time to let her go?
