All major tribble organizations within the Federation hold shows, where owners of tribbles compete for ribbons, awards, and even money.
Any healthy tribble is eligible for entrance in the shows, but the owner must be a member of one of the tribble organizations, and an NTBC (Non-Breeding Tribble Certificate) is required.
Breeding tribbles have their own shows, which is usually an excellent place to find a good, healthy tribble. Breeders will usually have several 'safe' tribbles with them as well, for showing requirements and for sale. At larger shows, there might even be an auction of breeding and non-breeding tribbles.
Most shows are divided in the following classes:
-Miniatures, all colors, all coats.
-regular tribbles, short haired.
-regular tribbles, rough haired.
-regular tribbles, long haired.
-giant tribbles, all colors, all coats.
-natural colored tribbles.
-exotic colored tribbles.
-grand and reserve champion, chosen from the first and second places in each class.
A tribble can be entered in more than one class if the judging schedule permits. For example, a shorthair, blue regular can be entered in the regular, short haired, class as well as in the exotic colored class.
Tribbles are judged on general health, condition, size according to breed and age, brightness of color, and texture and condition of hair coat. Breeding tribbles are also judged on health, number, color and size of offspring. (Breeders should bring a recent litter along with the parent to compete in any class)
Any tribble association can provide information on local shows, dates, and specific requirements (if any).
