This webinar will guide us through the diagnostic approach of the ‘yellow cat’, mentioning some of the fascinating particularities of the feline species. Whilst icterus can be a very noticeable clinical sign that is straightforward to identify, it is not pathognomonic of a specific disease. Understanding bilirubin metabolism is indispensable in classifying icterus and building the differential diagnosis list which will guide the investigations. As we all are very aware, cats are not small dogs! Their metabolic and anatomical characteristics impact the type of pathology we observe in practice. Amongst other differences, cats are strict carnivores and are less adaptable when protein intake decreases. Their common bile duct joins the pancreatic duct before entering the duodenum, which may increase the risk of ascending bacterial infection. Feline characteristics are also important to bear in mind when interpreting blood and urine laboratorial analysis. This webinar is provided by BSAVA Education Partner IDEXX.
