Can we sacrifice cattle whose deciduous teeth are not replaced? We have sacrificed one without checking the teeth and later found out that it still had deciduous teeth in its mouth.
Having lost the deciduous (milk) teeth is certain evidence that the animal has completed its first age. However, a one year old animal may still have its deciduous teeth. Therefore, it is difficult to make comment. Anyway, if it is certain that the animal is not yet of one year old, this worship is supposed to be charity, rather than sacrifice.
