What are the reasons for a cat's loss of appetite and weight loss?

A cat's loss of appetite and weight loss may be caused by factors such as picky eating, dental caries, intestinal parasite infection, gastroenteritis, and diabetes. First, if the lack of appetite is caused by picky eating, which is a normal physiological phenomenon, owners generally do not need to worry too much. However, if the cat shows other uncomfortable reactions, such as bloating, increased bowel movements, and polyuria, it is recommended to take the cat to a regular hospital for treatment in a timely manner.

Picky Eating

If a cat often exhibits picky eating, it means that the food being fed is not to its liking. You can try changing the cat food and cat cans to varieties that it enjoys, which can increase its appetite and help resolve the issue of loss of appetite. This, in turn, will help the cat regain its normal weight.

Dental Caries

This is usually caused by poor oral hygiene. Symptoms include bad breath, drooling, and swollen gums. Eating may cause even greater pain, leading to a decrease in appetite and weight loss. Treatment usually involves taking antibiotics and non-steroidal anti-inflammatory drugs under a doctor's guidance. In severe cases, tooth extraction may be necessary.

Intestinal Parasite Infection

This is mainly caused by intestinal parasites, which can cause damage to the gastrointestinal tract, affecting normal appetite and leading to symptoms such as loss of appetite, abdominal pain, and vomiting. Treatment usually involves taking veterinarian-prescribed deworming medications.

Gastroenteritis

This is usually caused by pathogenic microbial infections, such as fungi and viruses. Symptoms include vomiting, increased gas, diarrhea, and even affect the body's absorption of nutrients, leading to weight changes. Treatment usually involves taking antifungal and antiviral medications as prescribed. When diarrhea is severe, antidiarrheal medications may also be necessary.

Diabetes

This is a metabolic disorder characterized by symptoms such as polyphagia, polyuria, polydipsia, and weight loss. It can also affect normal appetite. Treatment usually involves taking medications prescribed by a veterinarian to control blood sugar levels.
