Can Cats Drink Milk? A Filipino Pet Parent’s Guide
For many pet owners, the image of a cat lapping up a bowl of milk is cute and heartwarming.
But before pouring your muning a glass of milk, did you know that most felines are lactose intolerant? And that giving them the wrong kind of milk can be a bad idea? Let’s talk about it.
Most Adult Cats Are Lactose Intolerant
While kittens produce the enzyme lactase to digest their mother's milk, most cats lose this ability as they mature. Without lactase, cats struggle to digest lactose—the sugar in milk—leading to gastrointestinal issues like diarrhea, vomiting, and abdominal pain.
“Since they are unable to break down the lactose in dairy products, this leaves the lactose sugar in their system for the bacteria in their intestines to ferment,” Dr. Tawnia Shaw, DVM, of The Happy Pet Vet told PetMD. “The fermented bacteria are what give our pets intestinal cramps and diarrhea.”
What About Kittens?
Kittens are a different story—for a time. They can digest milk early in life, but ideally, they should nurse from their mother (or from other female cats). When that's not possible, never give them milk from other species such as cows, goats, and sheep.
Instead, kitten-specific milk replacers are recommended. One of the few approved by the Association of American Feed Control Officials (AAFCO) are PetAG KMR liquid milk supplement and PetAG KMR powder milk supplement.
While these milk replacers are derived from cow’s milk, they have been specially processed to reduce lactose, making it safe for a kuting’s sensitive stomach. The formulas also contain essential nutrients and calories for healthy development and include prebiotics and probiotics for digestive health.
PetAG KMR liquid milk supplement and PetAG KMR powder milk supplement can be fed to newborn kittens up to six weeks old, as well as to sick, undernourished, lactating, or senior cats.
Alternatives to Cow's Milk for Adult Cats
Once again, if your pusa wants a treat, avoid giving them cow’s milk, as well as oat milks, soy milks, almond milks, and coconut milks. These drinks can cause gastrointestinal problems due to the sugars, oils, and thickeners. The fat content can also lead to weight problems.
“... the high potassium levels can also lead to kidney troubles,” said Bondi Vet about coconut milk.
Instead, look for cat-specific milk products that are lactose-free. In the Philippines, Cosi Pet’s Milk is one such product, formulated to be gentle on feline stomachs.
Made in Australia, this lactose-free formula helps reduce the risk of digestive issues, bloating, and stomach discomfort. It’s also packed with essential nutrients like protein, calcium, and healthy fats to support strong bones and muscle development in growing kittens.
Final Verdict
Filipino pet parents may want to think twice before offering a saucer of milk to their pusa. Always opt for water as the main source of hydration, and if you must give milk, choose tummy-friendly options like PetAG KMR for kittens and Cosi's Pet Milk for adult cats.
As Marikina Veterinary Hospital advises, “Despite the classic image of cats drinking milk, most cats are lactose intolerant! Dairy can cause tummy troubles like diarrhea and gas. Stick to fresh water or lactose-free cat milk instead.”
And as always, don’t go overboard. Bondi Vet concluded: “While lactose-free milk is a safe option for cats, it should still only be given in moderation.”
When in doubt, consult your veterinarian so they can prescribe the right beverage for your muning. Better to be safe than sorry—especially when it comes to your furry friend!
