Cat Lost Appetite and Is Underweight

If your cat is underweight and refusing to eat, you should first take it to the vet for a comprehensive checkup, including tests for infectious diseases, complete blood count, detailed biochemical examinations, and additional auxiliary examinations such as X-rays and ultrasounds if necessary. If the cat is sick, it will be treated accordingly; if everything is normal, you can consider supplementing with trace elements and vitamins. There are various products on the market that can help improve appetite and facilitate nutrient absorption.

Reason 1 for Cat Refusing to Eat

The most common cause for a cat to suddenly stop eating is illness, such as gastrointestinal diseases like gastritis and enteritis, or infectious diseases like feline distemper and herpes virus. If your cat exhibits this behavior, you should promptly take it to an animal hospital for examination and treatment. Prolonged refusal to eat can lead to dehydration, electrolyte imbalance, and weight loss in cats.

Reason 2 for Cat Refusing to Eat

Switching cat food or changing cat dishes suddenly could lead to the cat refusing to eat. Inadequately fresh food or food the cat dislikes may also be factors. Oral diseases that cause difficulty swallowing can contribute to a cat's loss of appetite. Gastrointestinal discomfort or hairball syndrome等 diseases may also cause a cat to lose its appetite.

What to Do If Your Cat Refuses to Eat

If you have a young cat, you should first suspect whether it has an infectious disease. If it goes without food for a few days, it may die. You can give it some glucose by mouth and take it to the vet to check for infectious diseases. If none are found, it will need intravenous nutrition and anti-inflammatory treatment. If your cat is picky about food, you can try cooking some chicken breast to see if it regains its appetite. For adult cats, you should suspect whether it has swallowed foreign objects or has other internal organ problems, and take it to the vet for examination to determine the cause before implementing symptomatic treatment.
