Mine outlined the date that the animal was turned over to the person who would be doing the breeding, what was turned over and weight. That to best of both people's knowledge, both animals were free of internal and external parasites, and clearly stated the length of Quarantine.
Who was responsible to the care of the animal (enclosure, bedding, hydration, medical care, etc) and that if any health issued arised, I would be contacted immediately. The breeder also reserved the right to terminate breeding attempts if they felt that either animal was at a health risk.
There was also acknowledgement that some things happen that are out of our control, and a value was placed on the loaned animal in the event of its death and the period of time that restitution would be paid.
It outlined feeding schedule (frequency and what would be offered).
It listed the animal that it would be bred to and how the offspring would be divided (who chose first, and who got the extra odd animal if it wasn't an even number).
It stipulated how many times the babies would feed before the babies were split and the frequency of feeding the babies.
It also named the independent, non-affliated person who would sex the offspring, and stated that the offspring I chose as well as the loaned animaal would be packaged for overnight delivery and full and complete records would be kept and turned over to me at the time of the return of the animal.
