Quality of life

A way of judging whether a sick or elderly cat is still comfortable and enjoying life, used to guide end-of-life decisions.

Also called: quality of life scale, quality of life assessment, HHHHHMM scale, good days and bad days

Quality of life describes how well a cat feels from day to day. For an animal with a long-term or terminal illness, it is the main thing to judge. The question is whether the cat is still comfortable and able to do what matters to it, rather than only whether it is alive.

Vets and veterinary hospices offer checklists and scoring scales. One well-known example scores hurt, hunger, hydration, hygiene, happiness, mobility and whether there are more good days than bad. Each item is rated, and a low total, or a steady drop, helps owners and vets see when care is no longer working. Typical things to watch are pain, appetite, drinking, grooming, use of the litter box, ability to jump or walk, interest in the family, favorite spots and favorite foods.

Cats hide pain, so changes may be gradual and easy to miss. A calendar with a mark for each good or bad day, or short videos taken weekly, gives a clearer picture. Share the record at vet visits. Pain relief, nausea control, easier access to litter and bedding, and help with feeding can raise a score. When comfort cannot be restored, hospice care and euthanasia are discussed. Ask your vet to go through a scale with you, and to tell you honestly what the scores suggest.
