Cat Quality of Life Assessment
Including a Calculator to Help Guide Decisions
This assessment is based on the veterinary HHHHHMM Scale, along with honest, practical guidance on what your results mean and what to do next.
It won’t tell you what to decide. But it can help you see your cat’s situation more clearly when emotions make that hard.
Cat Quality of Life Calculator
Use the assessment below to evaluate your cat across all seven categories. Your results will include a total score, a per-category breakdown, and plain-language guidance on what each answer means.
Cat quality of life calculator based on the HHHHHMM veterinary scale
The quality of life calculator above is adapted from the HHHHHMM Scale developed by veterinary oncologist Dr. Alice Villalobos, published through the Veterinary Information Network (VIN). It is intended as an educational resource to support (not replace) a conversation with your veterinarian.
Why Cats Are Different to Assess
Every quality of life resource you’ll find online covers the same seven categories. What most of them don’t address is that cats present those categories in ways that are genuinely different from dogs. If you don’t know what you’re looking for, it’s easy to miss what your cat is telling you.
Cats hide pain and illness instinctively.
Cats naturally hide signs of pain and illness, so changes are often subtle. By the time discomfort becomes obvious, it may have been developing for weeks.
Open-mouth breathing while at rest is always an emergency in cats.
Unlike dogs, cats do not normally pant. Open-mouth breathing, panting, or labored breathing at rest is a sign of serious distress and requires immediate veterinary care.
Happiness looks different in cats.
Cats often show contentment quietly through slow blinks, purring, kneading, or simply choosing to be near you. If your cat suddenly stops seeking your company, hides more, or loses interest in favorite routines, those changes can be meaningful signs that something is wrong.
Quality of life is individual, even within the same species.
Every cat experiences illness differently. An independent cat may show happiness differently than one who always wants to be by your side. Use the score as a guide, but rely on what you know about your cat's personality, routines, and what brings them comfort.
The Problem With Just Using a Number
"A number alone doesn't make the decision."
A quality of life score helps organize what you’re seeing, but it doesn’t tell you when it’s time.
For example:
- A cat with noticeable weight loss may still be eating, seeking affection, and enjoying favorite activities. Their quality of life may be better than the number alone suggests.
- A cat with a reasonable score who has stopped grooming, interacting, and hiding constantly may be declining more than the numbers suggest.
Use the score as one piece of a larger picture. Bring it to your veterinarian. Let it inform the conversation.
What Each Category Really Looks Like in Cats
The seven categories of the HHHHHMM Scale cover distinct aspects of your cat’s daily experience.
Hurt: Pain and Breathing
Watch for:
- Open-mouth breathing or panting (an emergency)
- Hiding more than usual
- Reluctance to jump
- Crying or stiffness when handled
- Restlessness or unusual stillness
Cats often hide pain until it becomes significant.
Hunger: Appetite and Interest in Food
Loss of appetite often progresses gradually:
- Eating less
- Needing encouragement
- Refusing favorite foods
Cats that stop eating for more than 2–3 days can develop serious liver disease, so appetite loss should never be ignored.
Ask your veterinarian whether nausea treatment or appetite stimulants may help.
Hydration: Drinking and Fluid Status
Signs of dehydration include:
- Dry or tacky gums
- Skin that slowly returns when gently lifted
- Refusing water
Many cats with kidney disease benefit from fluids given at home. If your cat refuses water or prescribed fluids, contact your veterinarian the same day.
Hygiene: Grooming and Coat Health
Cats normally groom themselves.
When grooming stops, look for:
- Matted or greasy fur
- Dirty coat
- Pressure sores from lying in one position
Gentle grooming, clean bedding, and regular repositioning can help maintain comfort.
Happiness: Engagement and Contentment
Cats often show contentment quietly.
Look for changes such as:
- Hiding instead of staying nearby
- Less interest in family
- No longer slow-blinking, purring, or greeting you
Loss of these familiar behaviors can be an important sign that something has changed.
Mobility: Movement and Favorite Spots
Watch for:
- Jumping less
- Hesitating on stairs
- Difficulty using the litter box
- Spending less time in favorite high places
Ramps, orthopedic bedding, and low-entry litter boxes can improve comfort and independence.
More Good Days Than Bad
A “good day” doesn’t mean a perfect day. It means your cat experienced more comfort than distress.
Many caregivers find it helpful to track this daily over 1–2 weeks.
The overall pattern is more meaningful than any single day.
How to Interpret Your Score
The HHHHHMM Scale scores each category from 1 to 10 (our calculator uses a 1–5 scale per category, with a maximum of 35). A score above 25 generally reflects an acceptable quality of life. Below that, the specific areas where points are lowest are the places that deserve the most attention.
A few important things to hold alongside any score:
Your regular veterinarian should be your first call. They can evaluate your cat’s full medical history, current physical condition, prognosis, and what treatment or palliative care options remain. A quality of life assessment is most useful when it’s part of that conversation.
There is no exact formula for timing. Making the decision to say goodbye to a cat is incredibly challenging and often accompanied by feelings of guilt. While the scale gives you a structured way to look at your cat’s daily experience, many pet owners develop an intuitive sense of when it’s the right time for their pet and their family. That intuition matters. Both the data and your instincts belong in this process.
Two signs always require same-day contact with your veterinarian:
Labored breathing
Open-mouth breathing or panting is never normal in cats.
Refusing water
Dehydration moves quickly and causes its own suffering.
What To Do After a Quality of Life Assessment
A quality of life assessment is the beginning of a process.
If your cat’s score is stable, continue monitoring and reassess every few weeks, especially if they have a progressive illness.
If your score raises concerns, ask your veterinarian:
- Is there anything we haven’t tried?
- Would pain management, appetite support, palliative care, or hospice improve comfort?
These treatments focus on reducing suffering and helping your cat enjoy the best quality of life possible.
If your cat is in significant distress, contact your veterinarian the same day.
If travel is especially stressful for your cat, ask whether in-home care is an option.
About the Timing Decision
When families ask us about when it’s time, we don’t offer a formula because there isn’t one.
There's no number that answers that question."
Most people aren’t just asking whether their cat is okay.
They’re asking, “Is it time?”
There is no score that answers that question.
The best decisions come from three things:
- Your observations
- Your veterinarian’s guidance
- Your understanding of your cat’s daily life
Trust what you’ve learned from years of knowing your cat. Both the data and your instincts matter.
