Rats.

With approaches such as zinc finger nucleases, stem cells, and transposon mutagenesis, rats are becoming more popular as lab animals, reports The Boston Globe.

Fox Foundation has been pushing for rat models of Parkinson's disease as mice don't show the same disease symptoms as people. "To what degree the rat will replace the mouse remains to be seen," says Iva Morse, a corporate vice president for research model services at Charles River Laboratories.
