My feral cats aren't eating. What's wrong, and what can I do?

No, it's normal for cats not to eat, and it could be they have gotten sick from being out in the cold. They could have developed a respiratory infection, making them congested. When cats are congested, they can't smell their food, and that will keep them from eating. The problem with cats not eating is that if they go longer than three days without eating, they are prone to developing a fatty liver. I would take all three cats into the vet tomorrow for an exam. If they do have a respiratory infection, they may need antibiotics to treat it. You can try to tempt them to eat, in the meantime, by gently warming up really smelly wet food, such as sardine or fish based. You can also starting them on an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight.
