Minimally invasive laparotomy using a small incision and ring retractor (Figure 1) was subsequently performed under general anaesthetic to acquire hepatic biopsies and bile aspirate. The gross appearance of the liver was suggestive of multifocal abscessation (Figure 1.) After sample acquisition the cat was placed on potentiated amoxicillin (20 mg/kg IV q8h) as broad-spectrum empiric treatment for a suspected bacterial hepatitis.
