Cats with kidney disease often stop eating as much, which makes caring for them a lot tougher. An appetite stimulant can encourage cats with kidney issues to eat more, supporting their nutrition and general health. Appetite loss pops up a lot in these cats, so choosing the right approach really matters.
Mirtazapine is one of the top appetite stimulants for cats dealing with kidney disease.
It not only helps boost hunger but also eases nausea, which often tags along with kidney trouble.
That makes it a pretty solid choice for cats who struggle to eat because of ongoing kidney problems.
This article covers how appetite stimulants work, why they matter for kidney cats, and which options seem to work best.
The goal is to give pet owners some clear, helpful info to improve their cat’s daily life.
Understanding Appetite Issues in Cats With Kidney Disease
Cats with kidney problems usually eat less or seem bored with their food.
This can cause weight loss and make things worse for their health.
If you know why their appetite drops and how kidney disease changes nutrition, you can take better care of your cat.
Causes of Poor Appetite
A bunch of things can make cats with chronic kidney disease (CKD) lose their appetite.
Nausea and vomiting from waste buildup in the blood often make food seem unappealing.
High blood pressure and pain from kidney inflammation can also lower hunger.
Other reasons include dehydration and changes in taste or smell due to kidney failure.
Sometimes, medications or changes in the cat’s surroundings play a role.
Cats with CKD might develop anorexia, which makes it even harder to keep a healthy weight.
Diagnosing Appetite Loss
Vets usually run tests like blood work and urinalysis to check kidney function when a cat starts eating less.
These tests show if toxins are building up and how well the kidneys are doing their job.
They’ll also look for signs like vomiting, dehydration, and weight loss.
Blood pressure checks are common since high blood pressure often goes hand in hand with kidney trouble.
Figuring out the exact cause helps your vet decide if appetite stimulants or other treatments are the way to go.
Impact of Chronic Kidney Disease on Nutrition
Chronic kidney disease makes it tough for cats to process nutrients right.
Kidney failure can cause poor digestion and less absorption from food.
Even if the cat eats, weight loss can still happen.
Most cats with CKD need diets with less protein and phosphorus but more omega-3 fatty acids to help their kidneys.
Losing weight from poor nutrition can make kidney disease worse.
Careful nutrition is important to help cats stay as strong as possible during kidney problems.

Appetite Stimulants and Supportive Options for Kidney Cats
Cats with chronic kidney disease often lose their appetite, which makes things harder.
There are meds and careful care steps that can help get them eating again and support their health.
Knowing how these work and what’s safe really matters.
Mirtazapine and Capromorelin as Appetite Stimulants
Mirtazapine and capromorelin are two of the most common appetite stimulants for cats with kidney issues.
Mirtazapine blocks certain brain receptors to boost hunger and ease nausea.
You can get it as a transdermal gel or in oral form, which helps if your cat hates pills.
Capromorelin acts like ghrelin, the natural hormone that makes you feel hungry.
It wakes up the appetite center in the brain and also helps release growth hormone.
This drug is newer and comes as a flavored liquid you give by mouth.
Both drugs help cats eat more, so they can keep up their energy and weight.
Some studies show mirtazapine can help cats with kidney disease.
Capromorelin looks promising, but it’s still used more in dogs than cats.
Dosing, Administration, and Monitoring
Mirtazapine dosing depends on the form and the size of your cat.
You usually put the transdermal gel on the inner ear once a day, at about 1.88 mg.
Oral tablets or liquid usually run from 1.88 to 3.75 mg every 48 to 72 hours.
Capromorelin comes as a flavored liquid, with doses around 3 mg/kg once a day.
Give it by mouth with food to help your cat tolerate it better.
You’ll need to watch your cat’s appetite, weight, and mood every day.
Regular vet checkups are important to see how the kidneys are doing and to track side effects.
Oral dosing syringes can help you give capromorelin more accurately.
You might need to adjust the dose if your cat’s response changes or if there are side effects.
Don’t stop the drug suddenly, or your cat might lose their appetite again.
Potential Side Effects and Adverse Reactions
Both drugs can cause side effects.
Mirtazapine might lead to mild vomiting, more vocalizing, or drowsiness.
Rarely, cats can have allergic reactions like swelling or itching.
Capromorelin can cause drooling, soft poop, or mild tiredness.
Signs of overdose in either drug include agitation or a rapid heartbeat.
Cats with kidney disease are more sensitive, so if you notice anything odd, call your vet.
If your cat takes other meds or has other health issues, your vet should keep a close eye out for drug interactions.
Considerations With Other Health Conditions
Cats with diabetes need extra care when using appetite stimulants.
Mirtazapine can affect blood sugar, so you’ll want to monitor that closely.
Drugs like famotidine or monoamine oxidase inhibitors shouldn’t be used with mirtazapine because of possible interactions.
If your cat is on multiple treatments, they’ll need close vet supervision.
Sometimes, you can safely combine other supportive drugs, like anti-nausea medications, to help appetite.
Always share your cat’s full health history and medication list with the vet for the safest plan.
A few simple tips for dosing and handling meds can make things more comfortable for cats getting these stimulants or other treatments like ondansetron for cats.
