Buttermilk should be avoided for cats. Even though some cats seem attracted to dairy products, their digestive systems aren’t really fans of the concept. In adult cats, lactose intolerance is common, and a small amount can be enough to cause diarrhea, vomiting, or digestive discomfort.
Quick verdict
- For cats: avoid.
- Key takeaway: adult cats often digest lactose poorly, even in a fermented dairy product like buttermilk.
Buttermilk for cats: allowed, to be limited, or forbidden?
Buttermilk is not a suitable food for cats. The cat is a strict carnivore: its nutritional needs are mainly met by high-quality animal proteins, not by dairy products. A tiny accidental ingestion doesn’t necessarily cause an emergency, but it’s better not to offer it to them.
Is buttermilk dangerous or toxic for cats?
Buttermilk is not strictly toxic, but it can be dangerous for your cat’s digestive comfort. Many adult cats produce little lactase, the enzyme that breaks down lactose. Undigested lactose can then irritate the colon and quickly cause diarrhea.
What are the possible benefits?
The benefits of buttermilk for cats are very limited. Even if it contains some nutrients, they are not necessary in their diet.
- A slight intake of proteins or minerals, but with no real interest for a balanced feline diet.
- No sufficiently solid advantage to offset the digestive risk.
What are the risks to know?
The main risk is digestive, especially in sensitive or senior cats.
- Lactose: acute diarrhea, gas, discomfort, or vomiting.
- Unnecessary calories: low nutritional interest, especially for a sterilized or sedentary cat.
- Parts to avoid: the entire product should be avoided, particularly if it is sweetened, flavored, or unpasteurized.
How much to give your cat?
It’s best not to give buttermilk to a cat. If your cat accidentally drank a tiny amount, just monitor their digestion.
- Adult cat: avoid; no regular amount recommended.
- Sensitive cat: completely avoid, especially in case of frequent diarrhea.
- Kitten: avoid, unless specifically indicated by a vet with a milk replacer suitable for kittens.
Can my cat drink raw, pasteurized, or processed buttermilk?
Pasteurized buttermilk should still be avoided because of the lactose. Raw or unpasteurized buttermilk is even less recommended, as it can contain unwanted germs. Sweetened, flavored versions, or those included in fatty recipes, must also be ruled out.
How to prepare it properly?
- Do not prepare it for your cat: it’s not a useful food for them.
- Remove any dairy product left within reach, especially if your cat is curious.
- Favor a complete feline diet or a treat suitable for cats.
When should it be avoided?
- Kittens, as their needs are very specific.
- Senior cats, who often have a more fragile digestive system.
- Overweight, diabetic, or kidney disease cats, or those prone to digestive issues.
- Cats on medication or a veterinary diet.
My cat drank buttermilk: what should I do?
If your cat drank a small amount of buttermilk, remove the bowl, offer fresh water, and observe them. In case of a large amount, repeated vomiting, severe diarrhea, lethargy, or if your cat is fragile, contact your veterinarian.
What signs should you look out for?
Signs to watch for include vomiting, diarrhea, gas, abdominal pain, loss of appetite, or lethargy. With cats, it’s better not to wait if symptoms persist or worsen.
What are safer alternatives?
- A treat specially formulated for cats.
- A small piece of plain cooked meat, without salt or sauce.
- Complete wet food tailored to their needs.
