Cancer is a leading cause of death in older cats, and the welfare implications of different treatment approaches require careful consideration of quality of life alongside longevity.
Cats with cancer face welfare challenges from the disease itself and potentially from treatment. The decision between curative, palliative, and euthanasia approaches requires honest assessment of prognosis, treatment burdens, and quality of life. Aggressive treatment that extends life but significantly reduces quality of life may not be in the cat's best welfare interests. Palliative approaches that maximise comfort in the remaining time may better serve welfare in some cases.
