The basis of an andrological examination is the investigation of sex organ anatomy by clinical examination and ultrasound. However, systematic studies on the feline testis in larger numbers of animals are not yet available. Therefore, this study described the physi-ological sonomorphology of the cat testis and aimed to confirm the findings through histology and sperm production analysis. A clinical examination of the testicle was carried out in 33 European shorthair male cats as part of the preoperative examination before castration. The testes were sonographically examined (L 14–5 w) and measured in the longitudinal-transverse axis, and sagittal direction. In addition, the texture, echogenicity, and homogeneity of the testicular tissue were assessed. This was followed by castration and histological ex-amination. The testes were weighed and measured. The cat testicles show a characteristic sonomorphology. The parenchyma is homoge-neous with a distinct echogenic mediastinum. The histological exam-ination verified that it is active testicular tissue. The arithmetic mean for the testicle parameters, measured sonographically, is: length of right testicle 1.3 ± 0.2 cm, length of left testicle 1.4 ± 0.2 cm, width of right testicle 1.2 ± 0.1 cm; width of left testicle 1.2 ± 0.1 cm, depth of right testicle 1.0 ± 0.2 cm, depth of left testicle 1.0 ± 0.2 cm. The testicle volume of the right testicle is 0.93 ± 0.4 cm3 and of the left testicle 0.97 cm3± 0.4 cm3. The presence of sperm suggests the ani-mals were sexually adult. This study provides detailed testicular data for domestic cats, which has been verified by histological examina-tions, and can be used in the context of andrological examination
