When a Devon Rex cat refuses to eat, owners can try several methods to improve their appetite, such as providing probiotics, reducing treats, and regularly deworming. However, if the lack of appetite is due to illness, it is crucial to take the cat to a veterinarian as soon as possible.

Addressing Digestive Issues
1. If your cat has digestive discomfort, which can lead to a decreased appetite, consider giving them probiotics to help regulate their gut health. A good option is a multi-strain probiotic containing beneficial bacteria and prebiotics, which can effectively alleviate symptoms like soft stools, diarrhea, vomiting, and loss of appetite caused by an imbalance in gut flora. These products often come in convenient, individually packaged doses that are easy to carry, store, and administer.
Dietary and Behavioral Factors
2. Frequent feeding of treats can lead to picky eating habits in cats. Reducing the amount of treats you offer can help encourage your cat to eat their regular meals.
3. Oral health issues, such as dental problems or mouth infections, can also cause a cat to refuse food. If you suspect this is the case, seek veterinary care promptly.
4. Overly hot weather can diminish a cat’s appetite. Ensure your cat has access to a cool environment and plenty of fresh drinking water.
5. Internal parasites can also lead to a decrease in appetite. Regular deworming is essential to maintain your cat’s health and appetite.
6. If your cat is new to your home, they might be stressed or scared, leading to a temporary loss of appetite. Offer plenty of reassurance and help your cat become accustomed to their new environment gradually.
How Long Can a Cat Go Without Food?
A cat can typically go without food for about 2-3 days.
If a cat does not have any underlying medical conditions, a short period without food is generally not detrimental to their health as they will start to use stored fat. If water is available, a cat can survive without food for longer periods. Similar to humans, water is more essential than food for cats. Dehydration in cats will manifest in behaviors such as restlessness and agitation as water is vital for nutrient transport and bodily functions.
However, a week without any food can lead to severe health issues, such as hepatic lipidosis (fatty liver disease) and kidney problems, which can be life-threatening. If a cat has not eaten for an extended period, signs of hunger will include dull eyes, lethargy, and frequent vocalizations.
