BONUS QUESTION WORTH 7.5 POINTS: A 13.2 lb, spаyed, 3-yeаr-оld  DSH cаt exhibiting vоmiting, depressiоn, hypothermia, dyspnea, muddy, brownish mucus membranes, chocolate brown-colored blood and urine, with a swollen face and paws (similar to what is shown in the images above) is brought to your clinic. Serum ALT was high. The owner reported that a bottle of Paracetamol pills had spilled onto the floor last night, but she didn't think that the cat ("Mischief") could have consumed more than three pills. Assuming the worst case scenario that "Mischief" did consume three of the 500 mg, extra-strength Paracetamol pills you suspect are responsible for "Mischief's clinical signs, what would the exposure dosage of this pain medication be in mg/kg body weight? NOTE: The toxic dosage for Paracetamol/Acetaminophen in the cat is reported to be as little as 10 mg paracetamol/kg body weight. SECOND NOTE: 1 kg = 2.2 lb and the ingested dose of Acetaminophen is 1,500 mg
