# Feline Quality of Life Questionnaire: How to Use It A feline quality of life questionnaire is a structured set of questions that turns your daily observations of your cat into a score you can track over time. You answer questions about activity, appetite, mood, mobility, and grooming, then compare scores week to week. The results do not make decisions for you, but they give you and your veterinarian a shared picture of how your cat is doing. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Use a validated tool when one exists for your cat's condition, such as the FelQoL for general wellbeing [1], the CKD questionnaire for kidney disease [2], or the FeOA-QoL-TS-A for osteoarthritis [3]. - Score your cat at the same time of day, in the same room, and answer for the past week, not just today. - Track scores over time. A single low score matters less than a steady downward trend across several weeks. - Bring your completed questionnaire to veterinary visits so your cat's care plan reflects what you see at home. - Your own emotional state can color your answers, so ask a household member to score independently now and then [4]. ## How a Feline QoL Assessment Works Quality of life tools for cats measure two things: physical wellbeing and emotional wellbeing. The FelQoL questionnaire was built from responses from 1,324 cat owners in the USA and UK and produces seven dimensions covering daytime and mealtime behaviors, including Active, Talkative, Satisfied, Relaxed, and Mobile [1]. When the same cats were scored again two weeks later, the scores held steady, which means the tool measures something consistent instead of random daily ups and downs [1]. Disease-specific tools go deeper. The feline chronic kidney disease questionnaire started with 20 items, was refined through owner interviews, and ended as a 13-item instrument that measures owner-reported health-related quality of life in cats with CKD [2]. For cats with osteoarthritis, the FeOA-QoL-TS-A measures three separate things: the cat's quality of life, the owner's quality of life, and how satisfied the owner is with treatment [3]. That third piece matters because treatment satisfaction can affect whether you stick with a plan, and that affects your cat's outcome [3]. General tools and disease-specific tools answer different questions. Use a general tool like FelQoL for a broad baseline [1]. Use a disease-specific tool when your cat has a known diagnosis, because the questions target the symptoms that condition actually causes [2][3]. ## Step-by-Step: Using a Feline Quality of Life Questionnaire ### Step 1: Pick the right tool Ask your veterinarian which questionnaire fits your cat's diagnosis. If your cat has CKD, the 13-item CKD instrument is the validated choice [2]. If your cat has osteoarthritis, the FeOA-QoL-TS-A covers cat QoL, owner QoL, and treatment satisfaction in one form [3]. If your cat has several conditions or no single dominant diagnosis, a general tool like FelQoL gives you a broad baseline across seven dimensions [1]. ### Step 2: Set a scoring routine Score once a week on the same day. Pick a quiet moment when you are not rushed and your cat is awake and behaving normally. Answer for the past seven days, not just the last hour. The FelQoL dimensions were designed to be stable across a two-week window, so weekly scoring fits how the tool behaves [1]. ### Step 3: Answer honestly, not hopefully Owners tend to score their cats better than an outside observer would. In hyperthyroid cats, negative owner emotionality was linked to worse reported health-related quality of life, and having a comorbidity also affected scores [4]. Your mood and your cat's other diagnoses both shape what you see. Write down what your cat actually did this week, not what you wish were true. ### Step 4: Add a second scorer Once a month, have another adult in the household fill out the same questionnaire without seeing your answers. Compare the two. Large gaps usually mean one of you is missing behaviors the other notices, such as night pacing or litter box changes. This is not about who is right. It is about catching blind spots. ### Step 5: Bring the scores to your vet Take the last four to six scores to every recheck. Trends are more useful than single numbers. A cat that scored 80, 78, 75, 70 over a month tells a different story than a cat that scored 70, 72, 71, 70. ### Step 6: Pair scores with pain assessment Quality of life tools capture behavior and function. They do not replace a pain exam. The Feline Grimace Scale is a separate tool that scores ear position, eye position, muzzle tension, and whisker change [5]. In brachycephalic cats with ocular pain, reliability was excellent for ear and eye position but poor for muzzle tension and whiskers, so those two features are less trustworthy in flat-faced cats [5]. Your veterinarian can combine a QoL score with a pain score for a fuller picture. ## Sample Tracking Schedule | Timeframe | What to do | Why it matters | |---|---|---| | Once a week | Complete the full questionnaire | Builds a trend line you can compare | | Once a month | Have a second person score independently | Catches blind spots in your observations | | Every recheck | Bring the last 4 to 6 scores | Shows direction of change, not just a snapshot | | After any treatment change | Score again 1 to 2 weeks later | Shows whether the change helped | | Any sudden decline | Score today and call your vet | A sharp drop needs same-day input | ## Signs That Something Is Wrong A falling score is a signal, not a diagnosis. Watch for these specific changes and note how long they have lasted. - Your cat stops coming to the food area or stops vocalizing at mealtimes. The FelQoL tool treats mealtime behavior as a core dimension of wellbeing [1]. - Your cat is less mobile, jumps less, or hesitates on stairs. Mobility is one of the seven FelQoL dimensions [1], and it is a hallmark of osteoarthritis pain [3]. - Your cat hides more, sleeps in new places, or stops grooming. - Your cat's ear position or eye position changes in a way that looks like pain. These two features had good reliability on the Feline Grimace Scale, while muzzle and whisker changes were less reliable [5]. - Your cat's appetite, drinking, or litter box habits shift. In CKD, these changes are central to the disease and are built into the validated questionnaire [2]. If you see several of these at once, do not wait for the next scheduled score. Score today and call your veterinarian. ## Common Mistakes Owners Make **Scoring only on good days.** If you fill out the form after a great morning, your trend line will not reflect the hard days. Score on your regular day no matter how the week went. **Changing the routine.** Different times of day, different rooms, and different question versions all add noise. Keep the setup identical. **Treating one low score as the end.** A single bad week can come from weather, a houseguest, or a minor illness. Look at four to six scores before drawing conclusions. **Ignoring your own state of mind.** Owner personality and emotional state affect how owners rate their cats [4]. If you are exhausted or grieving, ask someone else to score too. **Using a general tool for a specific disease.** A general questionnaire may miss the symptoms that matter most in your cat's condition. Disease-specific tools exist for CKD [2] and osteoarthritis [3] for exactly this reason. **Skipping pain assessment.** QoL forms ask about behavior. Pain scales ask about facial expression and posture [5]. Use both. ## Supplies and Setup That Matter You do not need special equipment. You need consistency and a way to record answers. - A printed or digital copy of the questionnaire, always the same version. - A fixed day and time each week. - A quiet space where you can watch your cat for a few minutes before answering. - A simple log (paper, spreadsheet, or notes app) with the date and total score. - A note section for anything unusual that week, such as a vet visit, a new medication, or a change in food. - Your cat's medication list and dosing schedule, since treatment changes affect scores [4]. If your cat is a senior, review the [Cat Age Calculator: Feline Life Stages, Human Years Equivalence, and Senior Wellness Guide](/knowledge/veterinary-medicine/geriatrics/cat-age-calculator-feline-life-stages-guide) to understand which life stage you are scoring against. Nutrition changes can also shift energy and appetite, so the [Cat Food Nutrition: Choosing the Best Diet for Your Feline](/knowledge/veterinary-medicine/nutrition/cat-food-nutrition-guide) guide is a useful companion. For cats with several chronic conditions, [Feline Medical Advice For Senior Cats](/knowledge/veterinary-medicine/clinical-methods/feline-medical-advice-for-senior-cats) covers how overlapping problems are managed together. ## Limitations and When to Contact a Veterinarian No questionnaire diagnoses your cat. Scores reflect what you observe, and owner factors such as personality and emotional state can influence those observations [4]. Tools also have limits. The Feline Grimace Scale performed poorly for muzzle tension and whisker change in brachycephalic cats, which shows that even validated instruments do not work equally well in every cat [5]. A literature review of cat welfare tools found that most available instruments are context-specific or disease-specific, and some are not validated at all [6]. That is why a questionnaire supports your veterinarian's judgment instead of replacing it. Contact your veterinarian the same day if your cat stops eating for more than 24 hours, vomits repeatedly, strains to urinate, or cannot use the litter box normally. Go to an emergency clinic now if your cat is open-mouth breathing, collapsed, having seizures, bleeding, or crying out in pain. Schedule a routine visit if your scores have dropped for two or more weeks in a row, if your cat is hiding more, or if you are unsure whether a change is pain or just aging. Individual cases need a veterinarian who knows your cat's history, medications, and lab results. Bring your scores and let them guide the conversation. ## Frequently Asked Questions ### How often should I fill out a quality of life questionnaire? Once a week works well for most cats. The FelQoL dimensions stayed stable when cats were rescored after two weeks, so weekly scoring captures real change without picking up daily noise [1]. Score more often only if your veterinarian asks you to. ### Can a questionnaire tell me when it is time to say goodbye? No. It gives your veterinarian structured information about your cat's physical and emotional wellbeing, which supports the conversation. The decision also depends on your cat's diagnosis, treatment options, pain control, and your household's ability to provide care. Use the scores as one input, not the answer. ### Do I need a different questionnaire for each disease? Often, yes. Validated tools exist for chronic kidney disease [2] and osteoarthritis [3], and each targets the symptoms that condition causes. A general tool like FelQoL still works as a baseline across seven dimensions [1]. Ask your veterinarian which combination fits your cat. ### What if my cat's score drops but my cat seems fine? Look at the next two scores before worrying. A single dip can come from a stressful week, weather, or a minor issue. If the score stays low or keeps falling, call your veterinarian. Also consider that owners under emotional strain may rate their cats lower, so a second scorer can help clarify [4]. ### Does my own stress affect how I score my cat? Yes. Owner personality and emotional state are linked to how owners rate their cat's health-related quality of life [4]. That does not mean your observations are wrong. It means a second opinion from another household member adds useful perspective, especially during hard stretches of care. ## Related Articles - [OR Cat: Understanding Logical Health Decisions for Your Feline](/knowledge/veterinary-medicine/preventive-care/or-cat-logical-health) - [Cat Age Calculator: Feline Life Stages, Human Years Equivalence, and Senior Wellness Guide](/knowledge/veterinary-medicine/geriatrics/cat-age-calculator-feline-life-stages-guide) - [What Is a Titer Test for Dogs and Cats?
