My American Shorthair cat is only drinking water and not eating. What should I do?
If your cat is only drinking water and not eating, you should take it seriously, because cats don't stop eating for no reason.
1. Check and adjust the food
Sometimes pet owners don't check the cat food when feeding it. If the cat food is spoiled or has an odor, the cat may not want to eat it. If pet owners feed the same cat food for a long time, it is also easy for American Shorthair cats to get tired of it. If the cat is not eating due to food reasons, the solution is to adjust its diet. Do not feed it spoiled cat food. Try a different flavor and see if the cat will eat it. Also, do not only feed it cat food. Prepare some canned cat food and other food for it. 
II. Feeding cats cat-specific anti-aging products
Sometimes, cats eating too much or too many different foods at once can lead to indigestion. When their stomachs are bloated and uncomfortable, they may stop eating. Therefore, pet owners should feed their cats regularly and in moderation, avoiding uncontrolled feeding. It's also helpful to prepare digestive enzymes like "cat digestive aid" and mix them into their food. If your cat likes yogurt, you can also give them some, as this can also aid digestion.
3. Let your cat eat in a comfortable place.
Some cats may refuse to eat if they are disturbed while eating or if the eating environment is too noisy. It's important to let cats eat in a comfortable place. If guests come over or it's noisy, pet owners can prepare food for their cats in advance, but they shouldn't force them to eat. Once it's quiet or the guests have left, the tabby cat will probably go and feed itself, so there's no need to worry.
