Efforts have been made to endorse the thory of a viral aetiology for the feline urolithiasis syndrome (FUS) in the male cat. The presence of virus in the urine of three cases could not be confirned nor could the condition be transmitted by intra vesicular inoculation of urine from four affected cats into the bladders of normal cats. Following these negative findings work was done on SPF cats and a survey made of the incidence of urethral obstruction in six SPF cat units in England. No cases were reported from four of these units over a two-year period. Five cases occurred in the other two SPF units, three of which were associated with feeding an expanded dry cat food. There is, thus, no direct evidence that viral agents are involved in the aetiology of FUS.
人们已努力支持雄性猫科动物泌尿结石症综合征（FUS）的病毒病因学理论。在三例病例的尿液中未证实有病毒存在，将四只患病猫的尿液经膀胱内接种到正常猫的膀胱中也未能传播该病症。基于这些阴性结果，对无特定病原体（SPF）猫进行了研究，并对英国六个SPF猫饲养单位的尿道梗阻发生率进行了调查。在两年时间里，其中四个单位未报告任何病例。另外两个SPF单位出现了五例病例，其中三例与喂食膨化干猫粮有关。因此，没有直接证据表明病毒因子参与了FUS的病因。
