Understanding appropriate supplemental hydration options for felines is essential for any responsible pet owner.
While fresh water should always be the primary fluid source, certain other liquids can be offered occasionally as a treat or to encourage a cat with a low thirst drive to consume more fluids.
For instance, a small amount of unsalted bone broth can be an appealing and beneficial offering. Another example is commercially available milk formulated specifically for felines, which is processed to remove lactose.
These alternatives are not replacements for water but can serve as safe, intermittent supplements to a cat’s main hydration source, supporting overall health and well-being.
what can cats drink besides water
The cornerstone of feline hydration is, and always will be, fresh, clean water. It is vital for nearly every bodily function, from regulating temperature to flushing toxins from the kidneys.
A cat’s access to water should be constant and unrestricted, with bowls cleaned daily to prevent bacterial growth.
Before considering any other liquid, an owner must ensure their cat’s fundamental need for water is being met sufficiently.
All other beverages should be viewed strictly as supplements or occasional treats, never as a primary replacement for this essential resource.
One of the safest and most beneficial supplemental liquids for cats is plain, unsalted bone broth.
This nutrient-rich liquid can be made by simmering chicken or beef bones without any harmful seasonings like onions, garlic, or excessive salt.
Bone broth is highly palatable to most felines and contains collagen, glycine, and other minerals that can support joint health and digestion.
Serving it lukewarm can enhance its aroma, making it particularly enticing for picky drinkers or cats who are feeling unwell and have a reduced appetite.
While traditional cow’s milk is a poor choice for felines due to their common lactose intolerance, specially formulated “cat milk” is a viable alternative.
These products are widely available at pet stores and are treated to have most or all of the lactose removed, making them easily digestible.
They are often fortified with additional nutrients like taurine, which is essential for feline heart and eye health.
Despite their safety, these products are typically high in calories and should be offered in moderation as a special treat to prevent unwanted weight gain.
Goat’s milk is sometimes considered a more digestible option than cow’s milk for cats, as it contains slightly lower levels of lactose and has a different protein structure.

Some cats may tolerate it in small quantities without the digestive upsetsuch as diarrhea or stomach crampsthat cow’s milk can cause. However, it is not lactose-free and should still be introduced cautiously and served sparingly.
It is crucial to monitor a cat for any signs of gastrointestinal distress after consumption and to discontinue its use if any problems arise.
The liquid from canned tuna or salmon can be a highly effective way to tempt a cat to drink, but careful selection is paramount.
It is essential to choose fish packed in spring water, not oil or brine, and to verify that the product has no added salt or flavorings.
This fish-flavored water can be offered on its own in a small dish or mixed into a cat’s food to increase its moisture content.
Due to the potential for mercury content in tuna, this should be an infrequent treat rather than a daily supplement.
An often-overlooked source of hydration is a cat’s food itself.
Wet or canned cat food has a very high moisture content, typically around 75-80%, which closely mimics the moisture felines would get from their prey in the wild.
Switching a cat from a diet of dry kibble to one that includes wet food can dramatically increase their total daily fluid intake, promoting better urinary tract and kidney health.
For cats that are reluctant to drink from a bowl, incorporating wet food is one of the most effective strategies for ensuring proper hydration.
Conversely, a significant number of common household beverages are toxic or harmful to cats and must be strictly avoided. Caffeinated drinks like coffee, tea, and soda can cause restlessness, rapid breathing, and heart palpitations.
Alcoholic beverages are extremely dangerous, leading to intoxication, respiratory failure, and even death.
Furthermore, sugary drinks such as fruit juice and soda provide no nutritional value and can contribute to obesity and dental problems, while the artificial sweetener xylitol, found in some products, is highly toxic to pets.
Ultimately, before introducing any new liquid into a cat’s diet, consulting with a veterinarian is the most responsible course of action.
A veterinarian can provide guidance based on the cat’s specific age, health status, and dietary needs, ensuring any supplement is beneficial rather than harmful.
This is particularly critical for cats with pre-existing medical conditions, such as chronic kidney disease, diabetes, or food allergies. Professional advice helps prevent accidental digestive issues or the exacerbation of underlying health problems.
Key Considerations for Feline Hydration
-
Water is Paramount
It cannot be overstated that fresh water is the single most important liquid for a cat’s health. Alternative drinks should only ever be considered as supplements, not replacements.
These options can be useful for encouraging fluid intake in picky cats, providing enrichment, or offering a low-calorie treat.
However, a cat’s primary drinking bowl should always be filled with clean water, and its availability should never be restricted. The goal of offering other liquids is to augment, not substitute, this essential hydration source.
-
Avoid Harmful Additives
Many human foods and broths contain ingredients that are toxic to cats. Onions, garlic, chives, and leeks, whether fresh, cooked, or powdered, can damage a cat’s red blood cells and lead to anemia.
High levels of sodium can cause salt poisoning, and artificial sweeteners like xylitol are extremely dangerous.
When preparing something like bone broth or offering tuna juice, it is imperative to ensure it is completely free of these seasonings and additives to keep the cat safe.
-
Lactose Intolerance is Common
While kittens produce the enzyme lactase to digest their mother’s milk, most adult cats lose this ability and become lactose intolerant.
Feeding an adult cat cow’s milk can lead to significant digestive upset, including diarrhea, gas, and abdominal pain.
This is why it is crucial to avoid dairy products and opt for specially formulated, lactose-free cat milk if a milky treat is desired.
Assuming a cat can drink milk like humans can is a common misconception that can lead to unnecessary discomfort for the animal.
-
Moderation is Crucial
Any liquid other than water contains calories and should be factored into a cat’s total daily intake to prevent obesity.
Even healthy options like bone broth or goat’s milk, when given in excess, can contribute to weight gain or create a nutritional imbalance.
These supplemental drinks should be treated as occasional treats, constituting no more than 10% of a cat’s daily caloric needs.
Over-reliance on these tasty alternatives might also make a cat less interested in drinking plain water, which should remain its primary hydration source.
-
Monitor for Adverse Reactions
Whenever a new food or liquid is introduced into a cat’s diet, it is essential to monitor the animal closely for any negative reactions.
Signs of digestive intolerance can include vomiting, diarrhea, lethargy, or a loss of appetite. If any of these symptoms appear after a cat consumes a new beverage, its use should be discontinued immediately.
Consulting a veterinarian is recommended if the symptoms are severe or persist for more than a day.
-
Consult a Veterinarian
Before making any significant changes to a pet’s diet, professional veterinary advice is invaluable. A veterinarian can assess a cat’s overall health and provide tailored recommendations that are safe and appropriate.
This step is especially important for felines with health issues like kidney disease, urinary problems, or diabetes, as their dietary and hydration needs are highly specific.
A professional can help an owner navigate the options and ensure that any supplemental liquid supports the cat’s health rather than compromising it.
Practical Tips for Offering Alternative Drinks
-
Serve at Room Temperature
Cats are often sensitive to temperature and may be hesitant to consume liquids that are served too cold.
A beverage offered at room temperature or slightly warmed is generally more appealing, as it mimics the temperature of natural prey.
Gently warming a liquid like bone broth can also enhance its aroma, making it more enticing to a cat with a discerning palate or a diminished sense of smell, which can be common in older felines.
Avoid serving liquids that are hot to prevent burns to the mouth.
-
Use a Shallow Dish
Many cats experience a condition known as “whisker fatigue,” where their sensitive whiskers repeatedly touch the sides of a deep bowl, causing discomfort or stress.
To make the drinking experience more pleasant, it is best to serve any liquid, including water and supplemental drinks, in a wide, shallow dish.
This allows the cat to drink comfortably without its whiskers being overstimulated, which can encourage them to consume more fluids.
Ceramic or stainless steel bowls are also preferable to plastic, as they are less likely to harbor bacteria.
-
Introduce New Liquids Slowly
To avoid overwhelming a cat’s digestive system, any new beverage should be introduced gradually.
Start by offering just a teaspoon or two to see how the cat responds and to check for any signs of an allergic reaction or digestive upset.
If the cat tolerates it well, the amount can be slowly increased over time.
This cautious approach minimizes the risk of adverse effects and allows the owner to gauge whether the cat even enjoys the new offering before purchasing or preparing it in larger quantities.
-
Create Hydrating “Soups”
A simple and effective method for boosting a cat’s fluid intake is to mix a small amount of a safe liquid directly into its food.
Adding a tablespoon of water, unsalted bone broth, or the water from a can of tuna to a cat’s wet or even dry food can create a hydrating “soup” or gravy.
This technique is especially useful for cats that are reluctant to drink from a bowl, as it ensures they consume more moisture with every meal.
It seamlessly integrates extra hydration into their existing routine without them even noticing.
Proper hydration is fundamental to a cat’s health, influencing everything from organ function to energy levels.
Water is the medium for most chemical processes in the body, including the transportation of essential nutrients to cells and the removal of metabolic waste products.
It also plays a critical role in lubricating joints, maintaining normal body temperature, and supporting cognitive function. Without adequate fluid intake, a cat’s entire system can become compromised, leading to serious health complications over time.
Recognizing the signs of dehydration is a crucial skill for any cat owner. Early indicators can be subtle, such as lethargy, dry gums, and a decrease in appetite.
A more definitive test is to gently pinch the skin between the cat’s shoulder blades; if it does not quickly spring back into place, the cat is likely dehydrated.
Other signs include sunken eyes and a reduction in urination. If any of these symptoms are observed, it is vital to contact a veterinarian immediately, as severe dehydration is a medical emergency.
Chronic low-level dehydration is a significant contributing factor to some of the most common feline health problems. The kidneys are particularly vulnerable, as they require sufficient water to filter toxins from the blood effectively.
Inadequate fluid intake can lead to the formation of highly concentrated urine, which increases the risk of developing urinary crystals, bladder stones, and feline lower urinary tract disease (FLUTD).
Ensuring a cat is well-hydrated is one of the most proactive steps an owner can take to protect its long-term urinary and renal health.
A cat’s inherent physiology, shaped by its desert-dwelling ancestors, contributes to its often-understated drinking habits.
These ancestors evolved to obtain most of their necessary moisture directly from their prey, resulting in a naturally low thirst drive.
Domestic cats have retained this trait, meaning they may not feel compelled to drink water until they are already slightly dehydrated.
This biological predisposition makes it even more important for owners to find creative and appealing ways to encourage fluid consumption.
Many cats are more attracted to moving water than to a stagnant bowl. This instinct may be related to the fact that, in the wild, still water is more likely to be contaminated.
Investing in a pet water fountain can be an excellent way to stimulate a cat’s natural curiosity and encourage more frequent drinking.
The circulation aerates the water, keeping it fresh and cool, while the sound and movement can be highly enticing. For many reluctant drinkers, a fountain can be a simple yet transformative solution.
The choice between wet and dry food has a profound impact on a cat’s hydration status.
Dry kibble typically contains only about 10% moisture, meaning a cat on a kibble-only diet must drink a substantial amount of water to meet its needs.
In contrast, wet food contains around 80% moisture, significantly contributing to a cat’s total daily fluid intake.
Therefore, incorporating wet food into a cat’s diet is a highly effective and natural way to promote better hydration from the inside out.
Hydration needs can change based on a cat’s age and health.
Senior cats, for instance, are more susceptible to dehydration due to a decreased sense of thirst and a higher likelihood of having conditions like kidney disease or hyperthyroidism.
Similarly, cats with diabetes may experience increased thirst and urination, requiring more water to stay balanced.
It is essential for owners of these cats to be especially vigilant about monitoring fluid intake and to work closely with their veterinarian to develop a tailored hydration plan.
Beyond the physical benefits, offering a safe and tasty liquid treat can be a positive bonding experience.
The act of providing something special, like a small saucer of warm bone broth, can strengthen the connection between a pet and its owner.
This form of enrichment provides mental stimulation and enjoyment for the cat, associating the owner with a pleasant and rewarding experience.
As long as it is done safely and in moderation, it can be a wonderful way to show affection while also supporting the cat’s well-being.
In conclusion, while water must remain the unchallenged primary source of hydration for all cats, certain other liquids can be offered safely to supplement their fluid intake.
Options like plain bone broth, lactose-free cat milk, and the water from canned fish can entice a picky cat to drink more and provide a form of enrichment.
The key lies in moderation, careful preparation to avoid harmful additives, and always prioritizing water.
By understanding both the safe alternatives and the significant dangers of improper liquids, owners can make informed decisions that promote the long-term health and happiness of their feline companions.
Frequently Asked Questions
John asks: “My cat absolutely loves milk, and I only give her a tiny bit from my cereal bowl. Is that small amount really that bad for her?”
Professional Answer: Hello John, it’s a common belief that cats love milk, but unfortunately, most adult cats are lactose intolerant.
This means they lack the enzyme needed to digest the sugar in cow’s milk, and even a small amount can cause digestive issues like diarrhea, gas, and stomach pain.
To be safe and avoid causing your cat discomfort, it’s best to avoid cow’s milk entirely.
If you’d like to offer a milky treat, consider purchasing a specially formulated, lactose-free “cat milk” from a pet store, which is designed to be easily digestible for felines.
