Milk and dairy products

Milk and dairy products are not toxic to cats but are inappropriate for most adult cats. After weaning, the majority of cats lose the ability to digest lactose — the sugar in milk — because they stop producing the enzyme lactase. Consuming milk or dairy causes lactose fermentation in the gut, leading to GI upset.

Important Notes

Not toxic: dairy does not contain compounds that harm cats biochemically

Lactose intolerance: most adult cats lack sufficient lactase to digest lactose, leading to vomiting and diarrhea

Fat content: cream, cheese, and full-fat products are high in fat and calories — can trigger pancreatitis or obesity with regular feeding

A small occasional lap of plain milk is unlikely to cause serious harm in a lactose-tolerant cat

Lactose-free cat milk is a safer alternative if you want to offer dairy; avoid cheese and cream as regular treats
