Important notes
This tool is a starting point for conversation, not a diagnosis. Quality of life is deeply personal. Only you and your veterinarian can decide what is right for your cat.
When bad days outnumber good days and a healthy human-animal bond is no longer possible, your cat's quality of life may be too low. If your cat is suffering needlessly, it may be time to consider the gift of a peaceful passing.
Always involve your veterinarian. A vet can assess pain control, hydration, and other factors you may not be able to measure at home. They can also help you understand treatment options and prognosis.
Based on the HHHHHMM Quality-of-Life Scale developed by Dr. Alice Villalobos, DVM — the veterinary standard for assessing quality of life in cats and dogs. A total above 35 out of 70 represents acceptable quality of life to continue with hospice care.

Cat Quality of Life Calculator: Score Your Cat on the HHHHHMM Scale

Seven questions, each scored 1 to 10. The total lands somewhere between 7 and 70. That’s the whole tool. It exists because when a cat is seriously ill, “is she still enjoying life?” is the hardest question an owner faces, and having a number to look at makes the conversation with your vet a little less abstract. Score each item honestly. You’ll get a total, a per-item breakdown, and a verdict that tells you whether the score sits above or below the 35-point line vets use as a hospice threshold.

The scale behind this calculator is called HHHHHMM, developed by Dr. Alice Villalobos. It’s a standard tool in veterinary palliative care. The seven letters stand for Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad. Each one captures a different slice of a cat’s daily experience, from pain control to whether she can reach the litter box on her own. No item is weighted more than any other. They all matter equally, and the total is what you and your vet work from.

 

How to Use the Cat Quality of Life Calculator

  1. Read each of the seven items and the short description underneath it.

  2. Drag the slider to score each item from 1 (unacceptable) to 10 (excellent). Be honest rather than optimistic.

  3. Watch the total in the results panel update as you move each slider.

  4. Check the verdict banner to see where the score lands.

  5. Look at the per-item breakdown table to spot the lowest scores, which are the areas to raise with your vet first.

  6. Read the interpretation notes for a plain-language summary of what the total suggests.

  7. Copy or share the result if you want to bring it to your next appointment.

  8. Re-score every few days. Quality of life shifts, and the tool is designed to be used over time, not once.

 

How the Cat Quality of Life Calculator Works

Each of the seven items is scored from 1 to 10, then all seven are added together. The total sits between 7 and 70, with a higher number meaning better quality of life.

Formula: QOL total = Hurt + Hunger + Hydration + Hygiene + Happiness + Mobility + More good days

The threshold most vets use is 35 out of 70. Above 35 means quality of life is considered acceptable for continued hospice or palliative care. At exactly 35, the score sits on the line and a vet conversation is strongly recommended. Below 35, the scale suggests quality of life may be too compromised, and it’s time to discuss options seriously.

 
Total scoreVerdictWhat it typically means
56 – 70ExcellentCat is thriving, continue current care
42 – 55GoodGood quality of life, keep going
36 – 41AcceptableAbove the threshold, monitor closely
25 – 35Below thresholdDiscuss hospice and palliative options with your vet
7 – 24CriticalCat may be suffering, speak with your vet soon

One item deserves special mention: Hurt. The scale counts difficulty breathing and unmanaged pain as urgent, separate from the total. A cat with a 4 in Hurt but 9s everywhere else still has a total of 58, which reads as excellent. That’s misleading. Breathing trouble always outranks the number, and it needs veterinary attention that same day.

Per-item status is shown on the breakdown table: 8 or above reads as Good, 5 to 7 as Fair, 3 to 4 as Poor, and 1 to 2 as Critical. The tool also flags your lowest-scoring items so you know where to focus first.

 

Worked Example: A 14-Year-Old Cat With Kidney Disease

Say your cat is 14, has chronic kidney disease, and has good days and bad days. You score her like this:

  1. Hurt: 6. Pain is mostly managed but she’s stiff in the mornings.

  2. Hunger: 7. She eats, though you have to coax her.

  3. Hydration: 5. The vet mentioned subcutaneous fluids.

  4. Hygiene: 8. She still grooms, with occasional help.

  5. Happiness: 7. She purrs when petted but sleeps more than she used to.

  6. Mobility: 5. Slow to get up, sometimes skips the litter box.

  7. More good days than bad: 6. Roughly 4 good days for every 2 bad ones.

Total: 6 + 7 + 5 + 8 + 7 + 5 + 6 = 44 out of 70.

That lands in the “good” band, above the 35-point threshold. The lowest scores are Hydration and Mobility at 5, which suggests the next vet visit should cover fluid support and joint pain. The number alone doesn’t decide anything. It gives you a starting point for that conversation. Re-score in two weeks and compare.

Frequently Asked Questions

What is the HHHHHMM quality of life scale?

It’s a seven-item assessment created by Dr. Alice Villalobos for pets in hospice or palliative care. Each item scores 1 to 10, giving a total between 7 and 70. Above 35 generally means quality of life is still acceptable.

 

What is a good quality of life score for a cat?

Above 35 out of 70 is the usual threshold for continued hospice care. Above 42 reads as good, and above 56 as excellent. Below 35 suggests the cat’s comfort is seriously compromised.

 

How do I know when to put my cat to sleep?

When bad days consistently outnumber good ones, and your cat can no longer do the things she once enjoyed. A score below 35 on this scale, combined with a vet’s assessment, is the usual signal that it’s time to have that conversation.

 

What does the score of 35 mean on the HHHHHMM scale?

It’s the threshold vets use to decide whether hospice care is still appropriate. A total above 35 means quality of life is generally considered acceptable. At exactly 35, it’s borderline, and a vet conversation is strongly recommended.

 

Should I score my cat when she’s having a bad day?

Yes. The scale is designed to be used on any day. If you only score on good days, the total will look falsely high. Track scores across a week or two and look at the pattern, not just one reading.

 

Can a cat recover from a low quality of life score?

Sometimes. A cat scoring low because of untreated pain or dehydration may climb back above 35 after a vet visit. The pattern matters most. A score that stays low despite care is a different signal from one that dips and then recovers.

 

What is the most important item on the HHHHHMM scale?

Hurt. Pain and difficulty breathing carry extra weight because they affect everything else. Breathing trouble in particular is an emergency, and it overrides whatever the other six items score.

 

How often should I re-score my cat?

Every two to three days for a cat in decline, or weekly for a stable hospice case. The scale works best as a tracking tool, not a one-time test. The trend over time tells you more than any single score.

 

Does a low score mean I should euthanise my cat?

Not on its own. The score is a conversation starter, not a decision. A total below 35 means it’s time to talk seriously with your vet about options, comfort, and what your cat’s daily experience is actually like.

 

Is this calculator a substitute for veterinary advice?

No. It’s a structured way to organise your own observations. Vets assess pain, hydration, and body condition in ways you can’t at home. Use the score to support a conversation with your vet, not to replace one.

Disclaimer

This calculator uses the HHHHHMM scale to help you organise your observations. It is not a veterinary diagnosis, and it does not decide whether your cat should receive continued treatment, hospice care, or euthanasia. Quality of life is deeply personal and only you and your veterinarian can decide what is right for your cat. If your cat is showing signs of unmanaged pain, difficulty breathing, or a rapid decline, contact your veterinarian or an emergency clinic now. The tool is intended to support a conversation with a professional, not replace one.
