A cat needs blood. Feline blood products aren’t readily available. You don’t have any cats that can supply the amount you need but there’s a dog who can donate. What do you do? Hope for the best, harvest some blood, and transfuse it into the cat. We’ll have to wait and see if there are any negative consequences to this trans-species donation of blood cells, but for now, it’s a great story from the hospital where I complete a senior preceptorship. Sometimes the greatest medicine comes from the leaps of desperation; hope this leap lands the kitty with a healthy body. I am a little concern about how this cat’s immune system, kidneys, and liver will process the alien DNA, but perhaps the cells can serve their good before the cat’s body eliminates the foreign cells.
