A cat over 3 pounds took an entire deworming tablet, which may exceed its recommended dose. The dose of deworming medication for each cat should be adjusted according to its weight. Excessive intake of deworming medication may cause adverse reactions in cats.

It is very important to observe the cat's behavior and physical condition. If your cat shows abnormal symptoms such as vomiting, diarrhea, or neurological symptoms, you should contact your veterinarian immediately for diagnosis and treatment. Your veterinarian may recommend infusion therapy for your cat to speed up drug elimination, reduce intracranial pressure, and protect the liver and kidneys.
