Pet Not Eating at End of Life: When to Consider Euthanasia

A pet not eating at the end of life can mean different things, from nausea or pain to the body winding down. A vet can help you sort that out and talk through what might keep them comfortable day to day.

If euthanasia has come up too, not eating can be part of that decision, on its own or alongside other changes, and we’ll share the questions we’d bring to that conversation. Appetite is also part of a quality-of-life scale for dogs and cats developed by veterinary oncologist Dr. Alice Villalobos.

Below, we cover how quickly to call a vet for a dog, a cat, or a rabbit; why pets stop eating near the end; what can help; how appetite fits into a quality-of-life assessment; and how to keep them comfortable. For the rest of the decisions that come with this stage, our guide to pet end-of-life planning brings them together in one place.

Key Takeaways

• Not eating near the end of life can have many causes, and a vet can help you understand what would make your pet more comfortable.
• How soon to call a vet depends on the animal, their age and their health, and that timing is about getting help.
• Vets have options for a dog or cat who isn’t eating, like anti-nausea medicine or capromorelin, which is FDA-approved to stimulate appetite in dogs and manage weight loss in cats with chronic kidney disease. However, none of these promises a pet will eat again.
• Offering food from your hand can help some dogs and cats. If a feeding tube comes up, ask a vet what a normal day with one would look like.
• Hunger is one of seven categories on Dr. Alice Villalobos’s HHHHHMM quality-of-life scale for dogs and cats.

When to Call a Vet About a Pet Not Eating

If your pet is a cat, a rabbit, a puppy, or a dog with a chronic condition, call a vet as soon as they stop eating. Call promptly, too, for a senior dog whose appetite drops suddenly. For a younger, healthy adult dog, see a vet if they skip more than one meal, or have other symptoms.

Cats are on that list because going without food for as little as a day can have a severe impact on a mature cat’s health.

In rabbits, not eating often goes hand in hand with GI stasis, a slowing of food through the gut. A rabbit who isn’t eating can go from just feeling poorly to developing a life-threatening illness in a matter of hours.

For birds, reptiles, guinea pigs, horses, and other animals, ask a vet who treats that species how soon they’d like to see them.

These windows are about when to get help. They don’t tell you how much time a pet has left.

What a Vet Looks For in a Pet Not Eating at End of Life

A vet will want to know why your pet isn’t eating, and for how long.

The first question for a dog: have they lost interest in food, or do they want to eat but can’t? If they want to eat but can’t, they may be having difficulty picking up, chewing, or swallowing food, which can come from a sore mouth, an oral tumor, or pain that makes it hard to reach their food. Vets also check a cat’s teeth and gums, since pain that accompanies dental disease can keep a cat from eating.

A pet’s age and health history change what a vet looks for. If there’s already a diagnosis, a vet can tell you how this fits with it.

If you’re in this right now, here’s the question we’d bring to a vet: what would help them feel more comfortable? The answer might be medicine for nausea or pain, or comfort care and a conversation about euthanasia if you’re weighing it.

Why Pets Stop Eating Near the End of Life

Near the end of life, not eating often comes from how a pet feels: nausea, pain, a sore mouth, or the illness itself. More than one can be at play at once, and a vet can determine which ones are affecting your pet.

Nausea from any cause can make a cat lose their appetite. So can kidney disease or cancer.

Pain does the same thing, in dogs and cats alike. A tumor or pain anywhere in the body can make eating hard.

And sometimes it’s the end of life itself. PetMD describes how, in a dog’s final days, appetite and water intake will gradually decline as the dog’s organ systems begin to shut down, and for cats it lists weight loss, lethargy, hiding, and loss of appetite among the signs the end is near. A pet may skip meals but take a treat, or stop eating altogether.

What Can Help a Pet Not Eating at End of Life

A vet can treat nausea, prescribe appetite-stimulating medicine, manage pain, and add fluids. At home, small changes to the food and where you serve it can help too. None of these guarantees a pet will eat again, and what makes sense depends on why they stopped eating.

Medicine for Nausea, Appetite and Hydration

Nausea takes away appetite, and treating it can be part of the plan. Maropitant, sold as Cerenia, is an antiemetic used to treat vomiting in dogs and cats. Mirtazapine is another option that stimulates a cat’s appetite and also relieves nausea.

Capromorelin is known to increase appetite. For dogs, it’s sold as Entyce. For cats, it’s Elura, the first drug approved specifically for the management of weight loss in cats with chronic kidney disease. The FDA lists vomiting and drooling as the most common side effects seen in Elura’s studies. Whether any of these fit depends on your pet’s health and any other medicines they take.

Fluids given under the skin are generally well tolerated and can supplement what an ailing cat is drinking. For older dogs and cats, fluids can help them feel better.

Small Changes That Make Food Easier

Warmth and smell matter, and a few changes at home can help dogs and cats alike:

• Heat food to approximately body temperature (~100°F or 38°C), stirring well if you use a microwave.
• Rotate in a few different canned foods.
• A little plain, low-sodium chicken, beef, or vegetable broth can add flavor.
• For cats, try small, frequent meals of strong-smelling food in a quiet, warm spot.

For rabbits, a vet who knows rabbits can set a feeding plan, since their gut works differently. Some illnesses come with their own food rules too, so check with a vet on which changes fit. Our guide to gentle ways to help a terminal pet eat goes further into textures, flavors and hand-feeding at home.

Hand-Feeding, Syringe Feeding and Feeding Tubes

Hand-feeding is one option when a dog or cat cannot eat properly or willingly. A vet may also recommend a feeding tube, especially if a pet needs to take oral medication. A tube can make feeding and giving medicine easier for some pets. Tubes are often used to carry a pet until they can eat on their own. Near the end of life, goals can change, so it helps to ask what a tube would mean day to day: how long it would stay in, who would manage it, and how your pet is likely to handle it.

When a rabbit’s gut slows, treatment can include nutritional support (syringe feeding if not eating). If a vet recommends syringe feeding, they can show you how and help you monitor progress.

How Appetite Fits a Quality-of-Life Assessment

Appetite is one part of a bigger picture, and a quality-of-life scale gives you and a vet a shared way to talk about it. The HHHHHMM quality-of-life scale, developed by Dr. Villalobos, scores seven areas: Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More good days than bad.

Each area is scored from 1 to 10, with 10 being the best, and the scale is meant to guide a conversation with a vet. Our guide to the HHHHHMM quality of life scale walks through each area in plain terms. For cats, our daily cat quality-of-life checklist makes tracking simpler, one day at a time.

For anyone using the scale, a few habits make the hunger score more useful:

• Write down what they ate each day, treats included.
• Note whether they seem to want food but can’t manage it, or have lost interest.
• Score the other six areas the same day.
• Keep notes over time so a pattern can show.

If getting to a clinic is hard, our virtual support directory lists professionals who meet with pet parents online, and our quality-of-life consultations directory can help you find someone to talk it through with.

When Not Eating Is Part of the Euthanasia Decision

For some families, not eating becomes part of the euthanasia decision, on its own or alongside other changes in their pet’s comfort. Our guide to making the euthanasia decision walks through it, and a vet can help you think it over.

VCA’s quality-of-life guidance for cats puts it this way: when there are too many bad days in a row, or if the cat seems "turned off" to life, quality of life is compromised, and it asks, is the ailing cat still interacting with family members and with the environment? No single sign decides it.

Questions some families bring to that conversation:

• What would help them feel more comfortable right now?
• How are their pain and breathing?
• If we tried appetite medicine or a feeding tube, what would their days look like?
• What would comfort care, or saying goodbye, look like from here?
• Which changes would tell us things are moving faster than expected?

Our guides to when to consider euthanasia for a dog and when to consider euthanasia for a cat each include a way to track good days and bad days.

Keeping a Pet Who Has Stopped Eating Comfortable

Comfort care can be part of every day for a pet not eating at the end of life. The American Association of Feline Practitioners’ hospice brochure notes that you may have to move food, water, litter boxes etc. if your cat can’t get to them anymore, and the same goes for a dog: keeping food and water near the main resting area means less effort for them. Offer small amounts of something they love, at their own pace and without pressure, unless a vet has set a feeding plan.

Keep their spot warm and quiet, with company nearby if they seem to want it. Fluids, pain relief, and anti-nausea medicine can all be part of their care, even when the goal is no longer getting them to eat. Our guide to the difference between palliative care and hospice for pets explains how vets approach this stage, and the pet hospice providers in the Love, Baxter directory can help you plan care from here.

If you’d like the option of saying goodbye at home, our guide to finding in-home euthanasia services covers what to look for near you. Whatever their appetite does, warmth, quiet, and gentle care can be part of their days.
