This study used 3D landmark-based geometric morphometrics under an object-symmetry framework to quantify pelvic asymmetry in domestic cats and dogs while explicitly accounting for measurement error through replicate digitizations. Procrustes ANOVA revealed significant components of both directional asymmetry (DA) and fluctuating asymmetry (FA) in the overall dataset, and DA was further visualized as a structured, non-random pattern across the landmark configuration. Measurement error remained smaller than the FA component, yielding high repeatability, indicating that the detected asymmetry patterns were not driven by landmarking imprecision. Group-wise summaries are presented as descriptive patterns of the sample (rather than direct between-group inference). In these descriptive summaries, cats tended to show a more coherent DA pattern, whereas dogs showed greater individual variation consistent with a relatively stronger FA component; males also tended to exhibit greater FA-related dispersion than females. In regression models of FA, age showed no association, body mass exhibited only a weak trend, and sex emerged as a significant predictor, while species showed no detectable effect when covariates were included. Collectively, these results support the hypothesis that pelvic shape contains both systematic (DA) and individual-specific (FA) asymmetry components, with sex-related differences in FA magnitude, but limited evidence for age- or weight-related effects within the sampled range. The study provides a repeatable framework and baseline reference for pelvic asymmetry in cats and dogs.

Enterolithiasis is a rare gastrointestinal disorder characterized by mechanical obstruction caused by enteroliths formed within the intestinal lumen. Dietary composition, environmental factors, and breed predisposition have been reported to contribute to enterolith formation, with these structures typically developing through mineral accumulation around foreign materials. Although enterolithiasis is relatively common in horses, it has been rarely reported in cats and dogs. Surgical intervention is considered the most effective treatment option in clinically symptomatic cases. In this case report, two cats presented to our faculty clinic with complaints of lethargy and weight loss were evaluated. Hematological examinations revealed anemia in both cases. Abdominal radiographs demonstrated multiple similarly sized radiopaque structures within the small intestinal lumen. Surgical exploration revealed jejunoileal dilatation and ileocecal stenosis. In one case, removal of the enteroliths alone was sufficient, whereas the other case required enterotomy followed by segmental intestinal resection and anastomosis. These cases indicate that enterolithiasis should be considered among the differential diagnoses in patients presenting with chronic gastrointestinal signs and multiple radiopaque intestinal structures. The aim of this case report was to describe the clinical, radiographic, and surgical findings of enterolithiasis in two cats and to contribute to the limited literature regarding this rare condition in small animal practice.
