Solutions for cats experiencing indigestion:
1. If your cat has indigestion, you need to fast it for half a day or a day. If it vomits, you also need to withhold water. Then slowly feed it some softened cat food, porridge, or other easily digestible foods.
2. Owners can take their cats for walks. Appropriate exercise can speed up metabolism, promote digestion, and improve indigestion. 
3. Feed your cat some pet-specific probiotics to regulate its gut health and promote digestion.
4. If a cat is startled and experiences a stress reaction, it may also experience indigestion. In this case, comfort the cat and take it to a comfortable and quiet environment. It will gradually recover.
5. If the cat's condition is serious and it exhibits symptoms such as vomiting, diarrhea, or lethargy, it needs to be taken to a veterinary hospital for treatment as soon as possible.
