Fortunately, you shouldn’t be overly concerned since your cats drink apple juice. However, it is only ideal to drink apple juice up to a certain extent, after which it becomes detrimental to your feline friend due to the high sugar content present in the juice. There are no ‘cats apple juice’ or cat drinks made for them only.

Therefore, let’s go starlight ahead and explain whether cats can drink apple juice, and if so, in what quantities.

Can Your Cat Drink Apple Juice? (Expert Opinion) 

The simple answer is, yes, your cats can drink apple juice up to a few sips according to Barbara Read. However, this should only be allowed because apple juice can be toxic if they drink in great volumes.

The main reason for this is that they are primarily carnivorous, a cat’s diet mainly consists of meat, and they usually have a hard time digesting apple juice or foods that aren’t wholly meat. Therefore something other than meat confuses the cat’s system.

The cat’s digestive system, through the many years, has evolved to become very specialized at digesting and processing meat. But it isn’t well-placed to digest vegetables and fruits. Because of this, consuming apple juice leads them to an upset stomach.

And by allowing cats drink apple juice, which is rich in antioxidants and high sugar content, your feline friend will largely be unable to digest them.

To some of the essential nutrients such as vitamins, cats eat sources such as the liver that comprise the best cat food. This means your feline friend doesn’t need to have apple juice incorporated into their diet.

And with feline obesity becoming a huge worry for many cats due to high sugar intake, it’s your duty as a responsible cat owner to ensure your cat doesn’t have apple juice at all or only in small quantities.

How Much Apple Juice or Apple Slices Is Too Much?

The added sugar present in the juice can cause diabetic problems in your cat. If you want to feed her apple juice, check the product label to have any harmful chemicals. 

If you think you can let your cats drink apple juice regularly by preparing puree out of fresh apples at home, then I am afraid you’re wrong. Even fresh apples contain natural sugar that poses a risk to your cat’s health.

The scenario is not at all the same in all cases. Different cats have different preferences. For example, some might like the juice, some eat apples because of the crunchiness while some cats have apple allergies.

Felines do not eat apples naturally. What excites them about apples is the crunch. Because of the crunchiness, they like to eat apples and continue to take bite after bite.

Cat owners know that kittens do not drink apple juice for sweetness. Their system lacks the taste buds for sweetness. Eating apples excessively might make it difficult for them to have other foods.

Giving them too much apple juice or adding juice to their regular diet might also lead to your feline friend becoming disinterested in other meals. As a result, they fail to get all their necessary nutrition. If you don’t stop giving your kitten apple juice, the major symptoms that will start to show include:

  • Vomiting
  • Constant urination
  • Inability to jump and reduced activity 
  • Increased thirst
  • Reduced appetite
  • Obesity

Due to all these adverse effects, it’s best only to give your furry friend low amounts of apple juice. To determine the best levels to give them, consult a vet or pay a visit to the nearest animal clinic.

Once your kitty starts drinking apple juice, start to note down every other food they eat. By doing this, you’ll be able to tell when they’re eating an excessive amount of sugar or carbs. Beware of apple poisoning!

A Cat’s Natural Diet Does Not Include Fruits

Kittens are called obligate carnivores. This means they are naturally meat-eaters. Cat requires high protein for their existence and that high protein comes from meat alone. Apple juice cannot meet that demand.

A little apple juice causes no harm. However, apple juice containing too much sugar is risky for your kitten if you feed her constantly.

Keep in mind not to give them any citrus fruits as it is toxic for cats! Citrus fruits include- lemon, orange, grapes, pomelo etc.

What Can Cats Drink Besides Water?

If you notice your feline friend is not drinking enough or does not like to drink water, there are several things you can do to make it more appealing. Goat milk can be a healthier option than apple juice as an alternative to water-

Goat Milk: Is it safe for cats?

Are you shocked to see that I suggest milk though they cannot digest it? Yes, you can let your cat have milk but not cow milk, of course. This is because the lactose content of cow’s meat is indigestible to cats.

But nature has given us goat’s milk. Goat’s milk has very low lactose content making it a safer alternative. In addition, it contains probiotics that help with your cat’s digestive health.

There are other healthy snack alternatives to apple juice if you want them to have a variety of options. An excellent guide to identifying the best treatment would be considered foods that cats eat even while in the wild. The most common healthy alternatives include:


It’s rich in fiber and low in calories, so it’s no surprise it’s an excellent pick for your cat’s diet. Pumpkins are effective and superb for treating abnormal cat stools or stinky stools. You can feed the pumpkin to your feline friend together with other treats to improve your cat’s health.

This is a healthy snack alternative for your kitten you should always consider. Spinach can be offered as dry food which is is rich in vitamin A, C, and K, as well as iron. If your kitten has experienced issues due to calcium oxalate bladder stones, spinach might not be a great option.


Rich in protein and omega-3 fatty acids, salmon is also a great choice as an alternative to apple juice. Ensure your salmon is well-cooked before serving it to your kitten, and be sure it will relish the delicious taste. You can also use it as cat treats to train your kitten to learn something new.

We recommend you to try wet food made with salmon. It is a very good choice if your kitten has given up on its regular diet. Once they start eating the wet food, mix it with their regular meal and serve them to eat.

Are Apples Bad For Cats? 

Apples are rich in antioxidants, fiber, and vitamins, thereby making them safe for your cat in moderation. Nonetheless, giving your cat too much apple juice might, in the long run, lead to harmful effects to your cat because the high sugar content leads to stomach upsets.

You might be giving your cat apple juice with the thought of introducing vitamins and fiber into their diet. But if this is the case, you’re better off feeding your cat an apple rather than the apple juice. Doing this will be a challenge because cats are primarily carnivores, less inclined to eat non-meaty foods.

If you are looking for creative ways to prepare an apple meal for your cat, there are many opportunities, they include- 

  • Slice your apples into small chewable pieces
  • Make a puree of fresh apples and serve with cat food.
  • Serve cubed apple pieces with cat food.
  • Do not let your cat have rotten apple pieces. If you notice the apple turning brown or appear rotten, throw it away. If you leave the apple pieces out for 30 minutes, this might cause your cat diarrhea.

When slicing the apple, make sure it’s small enough for your kitten to chew efficiently and not risk choking. For you to determine the ideal amount of apples to give your kitten, it’s best to seek veterinary advice. But on average, your kitten can eat four tiny apples each week and not experience any adverse side effects.

But when serving apples to your feline friend, you must make sure to remove the stems and leaves as these usually have toxic cyanide. Exposure to cyanide might lead to your feline experiencing difficulty to absorb oxygen, and these symptoms should start showing in around 15 minutes. Some of the common symptoms to look out for include;

  • The pupils dilating
  • Vomiting
  • Difficulty breathing 
  • Red gums

You should ensure your kitten doesn’t eat the apple seeds. Otherwise, apple seeds can either get stuck in their teeth or chock your kitten. If the apple seed sticks between your kitten’s teeth, it can be converted into hydrogen cyanide, which is very toxic to your feline as it hinders the cells from absorbing oxygen.

Therefore, it’s important to observe safe practices when serving apples to your kitten. This includes washing the apples before feeding them to remove all the chemicals and bacteria which might have been applied during its production.

You should also confirm that the apple fruit isn’t rotten because the stomachs of felines are extremely sensitive. The consumption of a rotten apple by your kitten can quickly result in stomach complications and diarrhea, thereby needing the vet’s intervention.


Cats are carnivores, also cats drink apple juice but this might not be ideal due to the high carb and sugar content. With that said, you can still give your feline small quantities of apple juice as a snack once you have the go-ahead from your vet.

If you don’t observe this, your kitten is prone to become obese and quickly gain weight or getting diabetic, which is more prevalent for older ones.

Due to these possible challenges, it’s advisable to give your feline something that they would naturally eat other than apple juice. This reduces the possibility of any adverse effect which would affect your cat’s overall well-being.
