Abstract Background Tremors have been reported as a neurological sign in cats with hepatic encephalopathy due to congenital portosystemic shunts (HE‐CPSS) or postattenuation neurological syndrome (PANS). Methods The clinical records of cats diagnosed with HE‐CPSS and manifesting tremors between 2003 and 2023 were retrospectively reviewed to characterise the clinical features of the tremors. Results Nineteen cats with HE‐CPSS were included, of which 17 manifested tremors at admission and two had PANS. Domestic shorthair was the most common breed (12/19). Tremors were the only neurological sign in six of the 19 cats. Tremor localisation was generalised (10/19) or focal to the head (8/19) or a limb (1/19). Most tremors were episodic and non‐intentional (15/19), occurring usually at rest with occasional intentional features (4/19). Of the 14 cats for which 1‐month follow‐up was available, tremors discontinued in nine after surgical or medical management. Limitations The limitations of this study included its retrospective nature and the lack of video recordings, brain magnetic resonance imaging and electrophysiological evaluation of tremors in all cases. Conclusions A diagnosis of HE‐CPSS or PANS should be considered in cats with generalised or focal tremors.
