* Lactose Intolerance: Most cats are lactose intolerant. This means they lack the enzyme lactase needed to break down lactose, the sugar in milk. Consuming milk, even fresh milk, can cause digestive upset like diarrhea, gas, and vomiting.
* Sour Milk is Worse: Sour milk has even more lactose than fresh milk, as bacteria have broken down the sugar. This means it's more likely to cause digestive problems in your cat.
* Possible Bacterial Growth: Sour milk can harbor harmful bacteria that could make your cat sick.
Instead of offering milk:
* Water is best: Water is the most important thing for your cat's hydration.
* Cat-specific foods: There are many commercially available cat foods and treats that provide the nutrition your cat needs.
* If you're unsure, ask your vet: Your vet can advise you on safe food options for your cat.
Remember, even if your cat seems to enjoy milk, it's not a healthy choice for them. Stick to water and cat-specific foods to keep your feline friend happy and healthy.
