A direct line to drug dosing information based on your pet’s MDR1 genotype from the leading experts

Learning your cat has the MDR1 mutation can raise critical questions: Is that flea and tick medication safe? What about pain relief or emergency treatments? WhisPurr™ provides trusted answers when every decision matters. WSU’s MDR1 test is the only one intended for medical diagnosis and treatment — because incorrect results can be deadly. With WhisPurr™, you also have trusted guidance for prescription and over-the-counter medications, and peace of mind knowing your pet’s safety comes first.
