Appetite Stimulant for Cats – Buying Guide 

Anorexia is the medical term for lack of appetite for food which happens in cats too. There are various reasons why our cats develop a distaste for food. These include stress, anxiety, an underlying medical condition like kidney disease or a digestive problem. It is vital that you consult your vet to treat the cause of a lack of appetite.

If your cat is eating but decreased its consumption, your cat could be dealing with partial anorexia. Pseudo anorexia is not really a lack of appetite but are caused by other things which include dental pain, unpalatable food, or environmental problems. In a multiple household, the runt of the litter is often bullied by larger cats.

The problem is when your cat is not eating anything at all which is the case with true anorexia. Cats can survive up to two weeks without food or up to 72 hours without water. Sick cats, elderly felines, and kittens won’t last that long. If your cat has not eaten for 24 hours, check with your vet on how to stimulate a cat’s appetite naturally or with medication or assisted feeding. 

What Happens When Cats Don’t Eat

Refusal to eat a regular healthy diet can quickly result in protein malnourishment and high acid and phosphorus levels that can cause stomach discomfort. If the lack of appetite is accompanied by vomiting, hairballs or virus may be behind it. Aside from lethargy, muscle loss, and dehydration, we also worry about our cat getting hepatic lipidosis, a serious liver disorder.

How Appetite Stimulants Can Help

Before anything, keep in mind that appetite stimulants should not be used to deter treatment of the underlying condition. We simply can’t feed Delectables to a cat suffering from dental problems without treating the malady. Likewise, Nutri-Cal can’t treat cancer, kidney disease, and whatever condition your cat is suffering from. 

But, these appetite stimulants help immensely in providing as much nourishment as possible to cats that are too weak or sickly to concern themselves with food. A lack of nourishment leads to more problems and can cause delays in recuperating. Even elderly cats and dying cats were revived and completed their treatments with the help of a good appetite stimulant for cats

How to Choose a Cat Appetite Stimulant

While most of the products reviewed in this list can be bought over the counter, it is advisable to consult with your veterinarian to determine the cause of feeding problems with your feline. You may first switch your cat’s diet from dry food to wet food. Wet cat food will also ensure your cat stays hydrated.

If your cat has a dental issue or digestive problems, you may opt for food with a rich, creamy consistency which will make it easier for your cat to consume and digest. You can also use liquid appetite stimulants when you need to syringe-feed your cat. Still, inducing your cat to voluntarily eat is better than force feeding.

Natural appetite stimulant for cats

Certain flavors are more appetite-stimulating for cats and these include sardine, tuna, seafood, and poultry. Appetite stimulants with a strong fishy odor can help renew a cat’s hunger and appetite for food.

B-vitamins are also common among appetite stimulants for cats as vitamin B supplement can stimulate your cat’s olfactory senses so they will get hungry for their food again. Warming their food also helps to make the food more aromatic to your cat

Pharmacological treatment for appetite issues

It is vital to try different natural appetite stimulants before medicating your cat. Your vet may recommend an OTC appetite stimulant with vitamins, minerals, protein, sugar, and fat to stabilize a cat for treatment. Only when deemed necessary should you turn to drugs for your cat

Your veterinarian may prescribe cyproheptadine or more commonly known as Periactin to stimulate your cat’s appetite. It is an antihistamine available in tablet, liquid, and gel. What it does is it blocks serotonin in the brain that may result in appetite stimulation.

Benzodiazepines, otherwise marketed as Valium or Diazepam is an antianxiety drug that is given intravenously for appetite stimulation. It does get a cat to eat but your cat may still not get enough nutrient requirements as the effects of valium are often short-lived. Also, Diazepam is known to cause liver disease in some cats.

For a long time, cat owners dealing with full or partial anorexic cats turn to either valium or cyproheptadine to stimulate their cats appetite. In recent years, mirtazapine drug or Remeron has been recommended for the purpose of appetite stimulation in healthy cats. It also helps reduce nausea.

Side Effects of Medication

Like all pharmacological drugs, prescribed appetite stimulants for cats also have adverse effects. Drowsiness is common when using Periactin or Valium. Mirtazapine can cause jitters, over-excitedness, hyperactivity, howling, and muscle twitching in some cats. Other adverse effects include rapid heart rate, high body temperature, and reduced urination.

Far less common is the use of anabolic steroids to increase a cat’s appetite. Stanozolol and nandrolone decanoate are some examples. However, the side effects are more serious than other prescribed appetite stimulants and can result in liver toxicity in cats and may even induce psychiatric side effects.

Assisted Feeding

After presenting your cat with ten different types of food with no luck, you may want to try liquid or gel supplements. Often you can simply rub the gel or paste on your cat’s lips and they will lick it clean. If this does not go well, you will have to use an instrument to get the nutrients into your cat’s body. Here are different ways to do it:

  • Syringe-feeding- You will have to purchase a feeding syringe which has larger and longer openings at the end so you can feed gruel to your cat. If you are having a hard time with large syringes, you can opt for a smaller syringe and give your cat liquid appetite stimulant instead. You also need to be calm and patient when syringe-feeding.

Note: Feed into the side of the mouth and give your cat time to swallow to avoid aspiration pneumonia.

  • Feeding tubes- The device utilized will be implanted into your cat so you can directly give food and water through the tubes. There are various types which include:
    • Oesophageal tube- Your cat will be sedated and the tube is inserted on the neck and runs down to the esophagus. This is the easiest method for assisted feeding.
    • Gastrostomy tube- General anaesthetic will be used on your cat and the tube will be inserted at the cat’s side into the stomach. Your cat won’t have to swallow.
    • Nasogastric tube- Anesthesia may or may not be used during the procedure of placing the tube in the nose running down to the stomach. This is suitable for short-term feeding of liquids only.

Frequently asked questions about appetite stimulants for cats

How to stimulate a cat’s appetite?

Cats often prefer wet cat food like seafood or poultry-flavored varieties. They are also more likely to eat in shallow, stainless steel bowls than in deep, plastic containers. Palatability may be an issue which can be solved by adding fish flakes or tuna juice in their food. If they have trouble chewing or digesting food, you may opt for pureed food.

Cats recuperating from illness, stress, anxiety, or surgery may be given OTC appetite stimulants to ensure they get the required nutrients. Senior cats and malnourished cats will also have renewed appetite using stimulants. In case of continued refusal to eat, pharmacological medication and assisted feeding may be necessary.

Does catnip stimulate a cat’s appetite?

Catnip is an herb available in fresh and dried forms. It creates a euphoric high in cats followed by an increase in appetite. However, when catnip is ingested it can act as a mild sedative accompanied by a decrease in appetite. 

Catnip may be given to healthy cats that have a temporary distaste for food. It may be that you recently switched to a different type of cat food and they are still adjusting to its taste. Catnip may help in this case.

If your cat has not been eating, it is not advisable for their gut health to give them catnip. You may instead use over-the-counter appetite stimulants for cats.

Still, appetite stimulants help with the peace of mind of cat owners and vets so the cat receives nourishment while undergoing treatment. It also promotes recovery.

How to stimulate an old cat’s appetite?

Old cats are more keen on consuming wet food and soft food. Dry food and stews with bits of chunks may be hard for older cats to ingest. As such, it may seem like they don’t want to eat when they are really hungry. Before you consider implanting a feeding tube on your cat, first consider if your cat could be sick.

Weight loss in older cats is often caused by certain illnesses like kidney and liver diseases. Some cats are suffering from life-threatening illnesses and still others have dental problems like losing their canine teeth. Appetite stimulants will help your cat get the nourishment it needs as your vet focuses on treating the medical condition causing the lack of appetite. 

Is there a natural appetite stimulant for cats?

You can add chicken broth or canned tuna juice in your cat’s food to make it more palatable. All-natural appetite stimulants like dried bonito flakes are also available and can be added on top of cat food to make it more tasty. Do consider the probability that your cat has Vitamin B deficiency. Supplementing your cat’s food with Vitamin B can help regulate its appetite.

Some cats also don’t like sharing their food with other cats so make sure every cat has a separate bowl. Ensure there is no danger when gaining access to their food and be sure the kitty litter is as far away from their food as possible.

What stimulates a cat’s appetite?

Cats will eat when they are hungry. If you have an indoor cat, ensure that it gets adequate daily exercise so that it will want to eat its next meal. While we want to ensure our cats eat healthy food, we must also consider serving palatable choices to them. Animal protein has the flavor that cats love so opt for turkey, chicken, and seafood for your cat than veggies and carbs.

Some appetite stimulants for cats contain fats, oils, and sugars. Keep in mind that these will provide the extra boost of calories and energy that lethargic cats need as well as those that are eating poorly. 

Is Vetalog an appetite stimulant for cats?

While increase in appetite is one of the known side effects of using corticosteroids, the reverse is true for triamcinolone. Triamcinolone Acetonide or Vetalog is not suggested for the treatment of lack of appetite. It leads to loss of appetite and can also worsen ulcers and cause vomiting, diarrhea, and even bloody diarrhea. Worse, anorexia is one of the adverse reactions of Vetalog. 

The injectable steroid is used to provide relief from allergies, inflammation, itchy skin, and pain. However, caution should be exercised when medicating with Vetalog. It should not be given to pregnant and lactating cats as well as those with diabetes, heart failure, and hypertension
