The little blue cat cannot eat chocolate. Cats absolutely cannot eat chocolate. Theobromine in chocolate contains methylxanthine. Cats cannot metabolize this substance after eating it. Once a large amount accumulates in the cat's body, it can easily cause diarrhea or vomiting, and in severe cases, it can be fatal.

What to do if a cat accidentally eats chocolate:

1. Stop feeding: Stop feeding the cat after discovering that it has eaten chocolate.

2. Drink a lot of water: You can give your cat a lot of drinking water to promote urination.

3. Inducing vomiting: The owner can press the cat’s abdomen slightly with his hands, or feed the cat some medicine that helps induce vomiting, forcing the cat to vomit out the chocolate remaining in the stomach.

4. Feed probiotics: The owner can properly feed the cat some probiotics that help promote gastrointestinal motility, digestion and absorption to regulate the gastrointestinal tract.

5. Send to the hospital for treatment: If there are obvious symptoms of poisoning, such as drooling, lack of energy, etc., it is recommended to take it to the pet hospital for diagnosis and treatment as soon as possible to avoid delaying treatment and causing other problems.
