The HHHHHMM Quality of Life Scale (developed by Dr. Alice Villalobos) adapted for cats. Rate each factor from 1 (severe problems) to 10 (no problems). This tool is especially useful for senior cats, cats with chronic illness, or when facing difficult care decisions. Cats are masters at hiding pain — be observant and honest in your ratings. Always discuss results with your veterinarian.
Cats instinctively hide pain and illness — a survival behavior inherited from their wild ancestors. By the time a cat shows obvious signs, they may have been suffering for weeks. Learning subtle signs helps you catch issues earlier and score the HHHHHMM scale more accurately.
The HHHHHMM scale provides a structured way to assess your cat's quality of life. Here's how to score each factor specifically for cats:
| Factor | Score 8–10 (Good) | Score 4–7 (Fair) | Score 1–3 (Poor) |
|---|---|---|---|
| Hurt | No pain, relaxed posture, purrs | Some discomfort, managed with meds | Unmanaged pain, hiding, grimacing |
| Hunger | Good appetite, eats normally | Eats with encouragement, picky | Refuses food, needs force-feeding |
| Hydration | Drinks well, skin snaps back | Needs sub-Q fluids occasionally | Severely dehydrated, needs daily fluids |
| Hygiene | Grooms self, uses litter box | Occasional accidents, less grooming | Soiled, matted, can't use litter box |
| Happiness | Purrs, seeks attention, plays | Less interactive, some interest | Withdrawn, no interest, depressed |
| Mobility | Walks, jumps to favorite spots | Slower, avoids some jumps | Can barely walk, can't reach food/water |
| More Good Days | Mostly good days | Mixed, some bad days | Bad days outnumber good |
We also have a Dog Quality of Life Calculator using the same HHHHHMM scale. For cat weight monitoring, try our Cat Weight Calculator or Cat BMI Calculator.
FAQs
The HHHHHMM scale (developed by Dr. Alice Villalobos) assesses seven factors: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad. Each is scored 1–10. A total of 35 or below may indicate poor quality of life; 50+ suggests reasonable quality. This scale works for both dogs and cats — always discuss results with your veterinarian.
Use this calculator for senior cats (11+ years), cats with chronic illness (kidney disease, hyperthyroidism, cancer, diabetes), or when facing difficult care decisions. It helps you objectively assess well-being and identify specific areas needing attention.
Cats are masters at hiding pain. Signs include: hiding more than usual, decreased grooming or over-grooming one area, loss of appetite, reluctance to jump, hunched posture, dilated pupils, aggression when touched, and changes in litter box habits. The Feline Grimace Scale is another validated tool for assessing pain in cats.
A score of 35 or below suggests significant quality of life concerns. This doesn't necessarily mean end-of-life decisions are needed immediately — it means you should discuss pain management, palliative care, and treatment options with your vet. Some factors (like pain) can often be improved with medication.
For cats with chronic illness or senior cats, assess every 1–2 weeks. Keep a journal of scores over time — trends matter more than any single score. A declining trend over several weeks is more concerning than one bad day.
Yes. The HHHHHMM scale was originally developed for dogs but is widely used for cats as well. The factors (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad) apply equally to cats. We also have a dedicated Dog Quality of Life Calculator.
Common issues include: chronic kidney disease (affects 30–40% of cats over 10), hyperthyroidism, arthritis (up to 90% of cats over 12), dental disease, diabetes, and cognitive dysfunction. Regular vet check-ups every 6 months catch these early.
Yes, in many cases. Pain medication, appetite stimulants, subcutaneous fluids, environmental modifications (ramps, heated beds, low-entry litter boxes), and treating underlying conditions can significantly improve scores. The goal is to identify which specific factors are low and address them.
