Cat quality of life scale
When an old or ill cat is nearing the end, the hardest question, whether she is still having more good days than bad, is also the hardest to see clearly through love and fear. This is a gentle version of the scale most vets use for exactly that: Dr. Alice Villalobos’s HHHHHMM scale. Score seven parts of her life, watch how the total moves over time, and bring what you see to your vet. It will not make the decision for you. It is only meant to help you look honestly, and to give you and your vet the same picture to talk about.
Score each area from 0 to 10
10 is as good as it gets for her, 0 is as bad. Answer for the last few days, honestly and gently.
Is her pain well controlled, and can she breathe comfortably? This one matters most.
Is she eating enough, with or without a little help?
Is she well hydrated, or often dry and needing fluids?
Can she stay clean, or is she soiling herself or getting sores?
Does she still show interest and seek out the family?
Can she get around, and reach her food, water, and litter box?
Are her good days still outnumbering the hard ones?
Her score today
35out of 70
A total of 35or below is Dr. Villalobos’s signal to pause and talk with your vet about her comfort and what may come next. This is a prompt for that conversation, not a verdict, and one honest score on a hard day is not a decision.
This is a reflection tool, not an answer. Its real value is the trend over days and weeks, and the honest picture it gives you to share with your vet, who is the person to help you carry the decision itself.
What the seven areas mean
The scale is built from seven parts, five H’s and two M’s, each scored from 0 to 10 with 10 being ideal. They are Dr. Villalobos’s, and this is what each one is asking you to weigh:
Hurt
Pain control and the ability to breathe come first. Is her pain well managed, and can she breathe comfortably? Trouble breathing outweighs everything else.
Hunger
Is she eating enough? Does hand-feeding help, or has she largely stopped?
Hydration
Is she staying hydrated, or often dry? Some cats need fluids given under the skin to keep up.
Hygiene
Can she keep herself clean, especially after using the box, or is she soiling herself and at risk of sores?
Happiness
Does she still express interest and joy, respond to you, and want to be near the family, or has she gone quiet and withdrawn?
Mobility
Can she get up and move to her food, water, and litter box on her own, or does she need help?
More good days than bad
Across the week, are the good days still outnumbering the hard ones? When bad days start to win, that is the trend that matters.
How to read the score
Add the seven together for a total out of 70. Dr. Villalobos’s published guidance is that “a total over 35 points represents acceptable life quality to continue” with comfort-focused, supportive care. That line is a starting point for a conversation, not a finish line. Two things matter more than the exact number.
The first is any single low score. A cat can total well above 35 and still be suffering in one way that overrides the rest: uncontrolled pain, or trouble breathing, counts on its own, whatever the other six say. The second is the direction of travel. One score is a snapshot; scored every few days, the scale shows you whether her good days are holding or quietly slipping away, which is the thing you actually need to know.
How often to check
There is no fixed schedule, only the pace of her illness. A cat holding steady needs only an occasional honest look. A cat whose kidneys or heart are failing may need one most evenings, and that is not morbid, it is simply paying attention. There is more on reading the trend, and on facing the decision itself with your vet, in the fuller guide to a senior cat’s quality of life.
A word on the fear of acting too soon
Most of us are far more afraid of choosing too early than too late, which is its own kind of trap, because it can leave a cat hurting while we wait to be certain. The people at Lap of Love put it in a way I have held onto: the decision should not be about ending suffering that has already occurred, but about preventing any suffering in the first place. And their plainest line, the one that cuts through the fear: above all, our pets do not deserve to hurt.
Common questions
What is the cat quality of life scale?
It is a simple scoring tool created by veterinary oncologist Dr. Alice Villalobos, known as the HHHHHMM scale. You score seven areas of your cat's life, Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad, from 0 to 10, and add them up. It is meant to make an overwhelming question a little more concrete, and to be shared with your vet.
What is a good quality of life score for a cat?
On Dr. Villalobos's scale, a total over 35 out of 70 is described as an acceptable quality of life to keep supporting. But the number is a guide, not a rule: a very low score in a single area, especially pain or breathing, matters on its own, and the trend over days and weeks tells you more than any one total.
How often should I check my cat's quality of life?
As often as her condition warrants. A stable cat may need only an occasional honest look, while a cat with a serious or advancing illness may benefit from a check every few days, or even daily. Scoring on the same rhythm lets you see the direction, which is the point.
Does a low score mean it is time to euthanize my cat?
No. This scale does not make that decision, and no single score should. A low or falling score is a signal to talk with your vet soon about her comfort and your options, and to keep tracking honestly. The decision itself belongs with your veterinarian, who knows your cat and can weigh what the number cannot.
Who created the HHHHHMM scale?
Dr. Alice Villalobos, a veterinary oncologist who founded Pawspice, a quality of life program for terminally ill pets. She published the scale in 2004 and it appears in her textbook Canine and Feline Geriatric Oncology.
Biscuit is sixteen, with tired kidneys, and mostly still herself: she scores high on the things that make her Biscuit and lower on the ones that ask her old body to work. I score her some evenings, not because the end is near, but because I would rather watch the line honestly than be caught out by my own hope one day. If you are here scoring your cat, you are already doing the kindest, hardest part of loving an old animal: paying attention.
