A Cat Owner Is Startled to Find His 7-Year-Old DSH

A cat owner is startled to find his 7-year-old DSH acutely lame on her rear limbs. After quickly searching several cat web sites for help, he becomes convinced that the loss in limb function is because of a blood clot ("saddle thrombus") . Taking the advice of an online blog acquaintance instead of consulting with a veterinarian, the owner treats the cat with high doses of buffered aspirin. Why is this poor choice to treat this pet?

A) Cats biotransform aspirin to quickly to be effective
B) Aspirin would break the thrombus into many microthrombi
C) Aspirin wouldn't degrade the thrombus effectively
D) The buffering on this type of aspirin decreases its ability as an anticoagulant
