Dr. Pedersen has also maintained a significant research program into the genetics of cats.  His primary interest has involved in identifying potential genetic associations with resistance to a highly fatal and common infectious disease of cats, feline infectious peritonitis (FIP).   This resistance involves both genetic factors involved with host immunity, as well as viral genetic factors that influence virus/host interactions.

In addition to genetic research into FIP, Dr. Pedersen has collaborated on several other studies involving genetic diversity of domestic cats as well as simple genetic diseases.
