I just wondered if anyone has any advice. A friends car has very low red blood cells and may need a transfusion, but she's been told there's no cat blood in the country. He is type AB so can take any cats blood, my cat is immunised so I have offered to take him in if need be. Are there any risks? I just offered without thinking because I would hope someone would do the same for my cat, but I want to make sure there's no risk to him.
