Cat that no longer eats: Causes related to appetite
The causes that are related to appetite are the most common and are not serious in themselves, it often takes simple corrective measures to put in place to get your cat eating normally again.
Here are the appetite-related causes that make your cat no longer want to eat:

- He eats elsewhere: If you have an outdoor cat, he probably eats elsewhere, whether at a neighbor’s house or animals such as cats or rodents. If you notice that he goes out often and doesn’t eat much but doesn’t behave differently and doesn’t even approach food, he’s probably already eaten.
- Stress: Cats are routine animals, they hate change. If a new animal has arrived or its environment has changed, it will take time to adapt so that it feels safe again.
