Case history and photos

History

A weanling Siamese housed with a small group of males.

Clinical Signs

Left testicle was not descended and could be seen/felt in the lower abdomen. The right testicle appeared normal.

Diagnosis

Unilateral cryptorchidism.

Treatment

Once the rat was old enough, at three months of age, he was neutered. Neither testicle appeared to be diseased.

Outcome

The young male recovered quickly from his neuter and continues to do well.

Photos
