My husband and I are members of TRIO. In one of their recent newsletter, they had a blurb about a book for children. While it is geared towards explaining transplant rather than concentrating on living donation, I thought I would provide this in case someone would find it of interest and use.
"Explaining transplant to children is made easier by a series of small and beautifully illustrated books by Stacy Ray Waibel who uses her poodle, Rudy, as the character who faces the transplant challenge. The series includes such titles as "Rudy Gets a Transplant", "Rudy's Check-Up" and "Rudy's Incredible Kidney Machine".
It's interesting in that, believe it or not, they do have the capability (at specialized centers, of course!) to do animal transplants. I have a friend who's cat needed a kidney transplant. It would certainly be expensive, but if she so desired, she could take it to New York and have it done. Problem is the "donor" cat does not survive the process. She said even if she could afford it, she couldn't bring herselfto do it and know that another animal was killed so that hers could live.
