The aim of this study was to describe the origin, measure and esqueletopy of celiac artery in domestic cats. The anatomical dissections were performed on 30 cadavers of adult cats, 15 male and 15 female, with a rostrum-sacral length of 47.9 cm and 46.6 cm respectively. Cats were positioned in right lateral decubit and a thoracic incision was made to remove the 6th and 7th ribs to cannulate the thoracic portion of aorta. The vascular system was washed with saline solution, fixated with 10% formaldehyde solution and then filled with coloured Petrolátex S-65. After five days emerged in 10% formaldehyde solution, all the animals were washed in current water. The celiac artery was “in situ” dissected and measured with a pachymeter. The celiac artery arose as a single artery in 15 (100%) females. In males the celiac artery arose as a single artery in 12 (80%) cats; in three (20%) cats we observed the presence of celiac-mesenteric trunk. The average length of the celiac artery in females was 1.32 cm, and originated at the level of the 13th thoracic vertebra in two (13.3%) animals, between the 13th and the 1st lumbar vertebra in one (6.7%) animal, at the level of 1st lumbar vertebra in six (40%) cats, and between the 1st and 2nd lumbar vertebra in six (40%) cats. The average length of the celiac artery in males was 1.27 cm, and originated at the level of 13th thoracic vertebra in three (20%) animals, between 13th thoracic vertebra and 1st lumbar vertebra in three (20%) animals, at the level of 1st lumbar vertebra in four (26.7%) animals, between 1st and 2nd lumbar vertebra in one (6.7%) and at the level of the 2nd lumbar vertebra in four (26.7%) animals. No relation was observed between the celiac length and the rostrum-sacral length in cats. The origin of the celiac artery is not gender dependent.
