Watson here, and recently I received a question that I couldn’t answer. The inquisitive person wanted to know if cats and dogs have the same blood types. They also wondered if humans could donate blood for their pets. Well, with a bit of research I am ready to answer.
Cats have three main blood types: A, B, and AB. About 90 percent of domestic cats in the U.S. have type A blood. In fact, when a transfusion is necessary the veterinarian will frequently use an in-house cat for the donor because type A is so common. There is no universal blood type for cats. Interestingly, the same trend of dominant A groups is seen in wild cats.
On rare occasions when no other options are available, a cat can receive a transfusion of dog blood. This is not a long-term solution and the risks of doing so may compromise the health of the cat. More research into long-term effects is presently underway.
Identified by “DEA” or Dog Erythrocyte Antigen, canine blood types are broken down into seven categories: DEA 1.1, DEA 1.2, DEA 3, DEA 4, DEA 5, DEA 7, and DEA 8. Dogs that are DEA 1.1 positive are universal recipients, while DEA 1.1 negative pooches (60 percents of greyhounds fall into this category) are universal donors.
Humans have 12 blood types: A, B, AB and O with Rh positive or Rh negative for each one. Unfortunately, the closest to human blood is pig blood, and using human blood for your cat or dog would be very unwise.
There are blood banks for animals and many pet owners donate their pet’s blood to help other animals who are in need. So, my curious reader, you now know about the life force that we call blood. Now you have to figure out what your type is.
XOXO Watson
