How long does it take for a cat to have a rat poison? The attack time may vary after a cat takes mouse poison. Generally speaking, cats may experience symptoms within 2-4 hours after taking rat poison, but may also experience symptoms within 24 hours.

The specific onset time should be judged based on the amount of intake, the type and toxicity of rat poison. If the cat consumes very little mouse dose, the cat may not show symptoms of poisoning.

The symptoms of cats poisoning by taking mouse poison include vomiting, foaming at the mouth, convulsions, difficulty breathing, depression, coughing, coma, rapid breathing, blood in the feces, and even suffocation.

If a cat is found to be poisoned by rat poison, the owner should immediately pour soapy water on the cat to induce vomiting and send it to the hospital for emergency treatment.
