Although the overall incidence of urethral obstruction is probably low, this condition is an important reason for emergency presentation of the male ferret. n the United States, urethral obstruction is most frequently caused by…
High dietary levels of oxalic acid or oxalates may promote urolith or bladder stone formation in herbivores like the guinea pig and tortoise. The following chart shows the oxalate content in 100 grams of selected raw foods.
Calcium is the most abundant mineral in the body, and the majority of total body calcium is found within bones and teeth. Most mammals make only one or two sets of teeth in a lifetime, however rabbit teeth continually grow throughout their lifetime. This continual tooth eruption plays an important role in the rabbit’s long-term calcium needs.
Urolithiasis is characterized by single or multiple calculi throughout the urinary tract or by the presence of sandy material within the bladder and urethra. Uroliths are fortunately more of a historical disease in the ferret, while calculi are still an important problem in rabbits and rodents.
Abnormal urine in the rabbit typically appears white and chalky or pigmented. These changes can be related to the unique metabolism of calcium in the rabbit. Rabbits absorb nearly all calcium ingested; therefore blood levels vary substantially with the calcium content of the diet…
Urethral obstruction is an important reason for emergency presentation of the male ferret. If not corrected, obstruction can result in severe metabolic disturbances, coma, and death.
Signs of complete urethral obstruction are usually not very subtle. Ferrets may strain violently or cry when attempting to urinate. Owners may misinterpret the straining observed as “constipation”, and tenesmus may even lead to diarrhea in some cases. Occasionally, a ferret with blockage will present for lethargy, weakness, anorexia, and even collapse without obvious signs of dysuria although the urinary bladder will be…
