A sudden loss of appetite in a cat that is otherwise normal may be caused by a variety of factors. Here are some common causes and suggestions: Indigestion: Cats may suffer from indigestion due to eating too much or inappropriate food, and may experience symptoms such as bloating and loss of appetite. At this time, you can feed the cat some probiotics to help regulate the gastrointestinal tract and promote digestion and absorption. Parasitic infection: If your cat is infected with parasites, such as gastrointestinal parasites, it may cause a loss of appetite. It is very important to deworm cats regularly. It is generally recommended that internal deworming be performed every 3 months and external deworming once a month.

Oral problems: Oral problems such as tooth pain or oral ulcers in cats may also cause them to be unwilling to eat. Check the condition of your cat’s mouth and seek medical attention promptly if there are any problems.

Environmental changes or stress: Cats are very sensitive animals. Environmental changes such as family changes, moving, new family members, etc. may cause them to feel stressed, thus affecting their appetite. In this case, it is necessary to give the cat some time to adapt to the new environment and provide a quiet and stable living environment. Change in food taste preference: Cats may refuse to eat because their preferred food taste has changed. You can try changing cat food brands or flavors to see how your cat reacts.
