According to an article in Hobbyfarms.com (sorry, I know I will read anything that has a link to the Cattletoday boards) http://www.hobbyfarms.com/livestock-and ... 15001.aspx
there are height standards to be a minii.....
"According to the International Miniature Cattle Breeders Society and Registry (IMCBSR), any bovine 3 years of age or older measuring 42 inches or under at its hips is a miniature; a second classification, "midsize miniature," exists for minis over 42 inches and up to 48 inches tall. International Miniature Zebu Association cattle, however, are measured behind their Brahma-type humps and mustn't exceed 42 inches at 3 years of age. The American Hereford Association stipulates that Miniature Herefords must tape 43 inches or smaller; "classic miniatures" can be up to 48 inches tall. Lowlines (Miniature Angus) may be 42 inches high, as can Dexter cows; Dexter bulls can be two inches taller."
A mature cow who is only 42 inches is smaller than a frame 1.
