An Urban Experience
Another VetCompassTM study characterised all disorders recorded in 3,584 cats from a study population comprised 142,576 cats attending 91 clinics in England (8). The
most common disorders recorded were periodontal disease (13.9%; 95% CI, 12.5-15.4),  ea infestation (8.0%; 95% CI, 7.0-8.9), obesity (6.7%; 95% CI, 5.7-7.6), heart murmur (5.0%; 95% CI, 4.1-5.8) and traumatic
injury (4.6%; 95% CI, 3.8-5.3). In relation to our questions of main interest, this study compared purebred and crossbred cats across the twenty most common disorders and identi ed that crossbreds had higher prevalence for two disorders (abscess [excluding cat bite abscess], P = 0.009; hyperthyroidism, P = 0.002) whereas purebreds had higher prevalence for one disorder (coat disorder;
P < 0.001; Table 2).
