Early last fall I was called to observe two kittens about one month old, owned by Leonard Strand of Gowrie, Iowa. They were from a litter of three, the mother and litter mate being normal, short-haired and grey in color. These two had good coats of long, yellow persian hair and their general condition was good. However, they exhibited a peculiar incoordination when attempting to walk.
