A cat was evaluated because of an 8-month history of inappropriate defecation on hardwood surfaces. The patient was a 5 year-old 3.5-kg (7.7-lb) neutered male Persian cat. The cat had been adopted from a rescue service 8 months before the evaluation and lived with the owner in a studio apartment. The cat had defecated outside the litter box since it was adopted; according to the previous owner, the cat had no history of inappropriate elimination. The cat had signs of pain during defecation, diarrhea,and hematochezia for approximately 3 months after adoption. A physical examination and blood, fecal, and urine analyses had been performed by the primary care veterinarian 6 months prior to evaluation at our clinic. Results of those tests had indicatedmildly low serum albumin concentration, high serum globulin concentration, and mild neutrophilia. The cat had negative results for FeLV and FIV tests. Other test findings were unremarkable. Differential diagnoses for the cat included maldigestion, inflammatory bowel disease, and neoplasia. Further diagnostic tests were recommended, but the owner declined. After treatment with metronidazole (10 mg/kg [4.5 mg/lb], PO, q 12 h for 4 weeks) and feeding of a hypoallergenic diet, diarrhea resolved and hematochezia was detected less frequently; however, the frequency of inappropriate defecation did not change.

机译：对猫进行了评估是因为在硬木表面上有8个月不适当排便的历史。该患者是一只5岁大的3.5公斤（7.7磅）绝育的雄性波斯猫。在评估前的8个月，这只猫已从救援机构被收养，并与主人一起住在一室公寓。自从被收养以来，这只猫在垃圾箱外面排便。根据先前的主人，这只猫没有不适当消除的病史。收养后约3个月，猫在排便，腹泻和便血期间出现疼痛迹象。初级保健兽医在我们诊所评估前6个月对他们进行了身体检查以及血液，粪便和尿液分析。这些测试的结果表明，血清白蛋白浓度低，血清球蛋白浓度高和中性粒细胞减少。这只猫的FeLV和FIV测试结果阴性。其他测试结果不明显。猫的鉴别诊断包括消化不良，炎症性肠病和瘤形成。建议进行进一步的诊断测试，但车主拒绝了。用甲硝唑（10 mg / kg [4.5 mg / lb]，PO，每12小时一次，持续4周）治疗并喂养低变应原性饮食后，腹泻得到缓解，并发现了便血的频率降低;但是，不适当排便的频率没有改变。
