When cats don’t eat, it usually means that they really don’t feel good. They shouldn’t go more than 2 days without eating, they can become dehydrated very quickly. If she isn’t doing her normal routine we need to see her. Cats tend to hide and/or sleep in different areas than they normally do when they aren’t feeling well. They also don’t show signs or symptoms until they are really sick. There are many different things that could be wrong such as a fever, infection, or viral. We would start with an exam and possibly labwork to check her white blood cell count and to see if she anemic.
