The live culture claim is not something we could source." source: Paw Multiverse (https://pawmultiverse.com), free to cite with a link --- # Can Cats Eat Yogurt? Dairy Is on the ASPCA Avoid List Published by Paw Multiverse (A.I.T. Multiverse Consulting Ltd) · Last updated 5 August 2026 Quick answer The ASPCA lists milk and dairy among people foods to avoid, saying it can “cause diarrhea or other digestive upset”. Yoghurt is dairy and falls inside that entry. There is no yoghurt entry in the Merck food hazards chapter. Taken from this page and its sources. Not veterinary advice. If your pet has already eaten some and seems unwell, [see who to call](https://pawmultiverse.com/pet-emergency/). **This page is not veterinary advice.** Paw Multiverse is not a veterinary practice. We cannot examine, diagnose or treat your animal. There are no doses here, no portion sizes, no feeding amounts and no treatment steps, on purpose. If your pet has eaten something you are worried about, or has changed in a way you cannot explain, ring your vet or your nearest emergency clinic and let them decide. [Full disclaimer](https://pawmultiverse.com/disclaimer/). Yoghurt sits under the same published heading as cheese and milk, and the published consequence is the same: digestive upset rather than poisoning. What makes yoghurt its own question is the claim that live cultures make it different. We went looking for that and did not find it. ## What is published The ASPCA lists milk and dairy among people foods to avoid, saying it can “cause diarrhea or other digestive upset”. Yoghurt is dairy and falls inside that entry. Source: [ASPCA Animal Poison Control, People Foods to Avoid Feeding Your Pets](https://www.aspca.org/pet-care/animal-poison-control/people-foods-avoid-feeding-your-pets) (read 5 Aug 2026). There is no yoghurt entry in the Merck food hazards chapter. Source: [Merck Veterinary Manual, Food Hazards](https://www.merckvetmanual.com/toxicology/food-hazards) (read 5 Aug 2026). ## The live cultures claim The argument runs that the bacteria in live yoghurt have already consumed some of the lactose, and that this makes yoghurt tolerable where milk is not. It is a chemically reasonable argument. It is also one that no veterinary publisher we could reach has made in print. The International Cat Care page on cats and milk, which is the natural place to look, returned 404 twice. So the claim is reported here as a claim. Notice what follows from that. If the mechanism is unsourced, then so is any advice built on top of it, including the advice that plain live yoghurt is a safe treat. This page therefore gives no such advice. The fact that decides most cat food questions is not about the food. International Cat Care states that “cats are what’s known as obligate carnivores, meaning they are dependent on a meat diet and can’t thrive or survive without it”, and that “as obligate carnivores, cats are less able to digest and use carbohydrates”. MSD gives the biochemistry: cats require dietary taurine, cannot convert beta carotene to vitamin A because they lack the necessary intestinal enzyme, require arachidonic acid which “is absent in vegetable oils and fats but found in fat from meat, poultry, and eggs”, and “cannot synthesize substantial amounts of niacin from tryptophan” the way dogs can.

Everything beyond that, including the live cultures argument that makes yoghurt sound like an exception, is unsourced as far as we could establish. Advertisement ## What we could not source for this page Everything below was attempted on 5 August 2026 and is written here rather than left as a silent gap. - International Cat Care publishes a page on cats and milk. The address returned 404 on both attempts, so the lactose claim everybody repeats is not sourced on this site. - No publisher we could reach gives a lactose tolerance figure for adult cats. - No publisher we could reach publishes a portion, a frequency or a maximum for any human food given to a cat, and neither do we. - No publisher we could reach discusses live cultures, residual lactose or fermented dairy in relation to cats. ## Where to go next The parent reference for every food on this site is [Can My Pet Eat It](https://pawmultiverse.com/can-my-pet-eat-it/), which carries every food and species pair in its reference table with the publisher and the date read.
