Cat quality of life scale

It’s based on the HHHHHMM scale developed by veterinary oncologist Dr. Alice Villalobos. Score each area from 0 to 10, where 0 is very poor and 10 is as good as it can be. Think about the last few days rather than a single moment. There are no wrong answers, and the score is a starting point for a conversation, not a decision.

Reading the HHHHHMM scale

Dr. Villalobos suggests that a total above 35 out of 70 means quality of life is generally acceptable, and that comfort care at home can be reasonable. A lower total suggests your cat is struggling in several areas. One very low score matters too: pain or breathing trouble that can’t be controlled affects everything else, whatever the total.

It can help to score on the same day each week, or every day when things are changing. Writing the numbers down lets you and your vet see the direction things are moving, which is often clearer than any one day.

Talking with your vet about end of life care

Your vet knows your cat’s condition and can tell you what is likely ahead. It’s fine to ask plainly. Questions many people find useful:

• Is my cat in pain, and can we control it better?
• What would a good day and a bad day look like with this illness?
• Are there treatments that would make my cat more comfortable, even if they don’t cure the illness?
• Which signs would tell us it’s time to talk about euthanasia?

Hospice or palliative care is an option for many cats. The goal shifts from cure to comfort: pain relief, anti-nausea medicine, appetite support, fluids given at home, soft bedding and easy access to food, water and the litter box. Some vets offer this care at home, and some specialize in it.

Thinking about when to euthanize a cat

Few decisions are harder. There is rarely one clear moment, and many people worry about acting too soon or too late. Signs that often lead owners and vets to this conversation include more bad days than good, pain or breathing difficulty that medicine no longer controls, refusing food for more than a day or two, and a cat who no longer seems like themselves. Your vet can explain what the procedure involves, whether it can happen at home, and how to plan for aftercare. Whatever you decide, choosing a peaceful end for a cat who is suffering is an act of care.
