The show rules are very specific on this matter. They state that a cat must be presented the first time it is called to the ring. The three call procedure is strictly a courtesy to exhibitors. Here again, you probably should talk to the judge on their desire in this matter.
Some judges prefer that the clerk give two calls.
If the exhibitor is not in the ring, the clerk should determine if the absent cat is owned by another clerk or a member of the show committee. If it is, they should make an effort to find the person and advise them of their call. IF the exhibitor is not engaged as indicated, the clerk should estimate when the judge will need the cat, and give a third call appro ximately one minute before the estimated time for judging. In special circumstances, where the judge has a tight airline schedule, two calls only may be required. If this is decided upon, the clerk should announce this criteria.
