Five lions and 25 domestic cats used in this study were injected with acrylic resin. We examined the bifurcation area of the internal and external carotid arteries arising from the common carotid artery, as well as the thyroid, occipital, ascending pharyngeal, lingual, facial, posterior auricular, superficial temporal and maxillary arteries. In both species, the internal carotid arteries were extremely small and were unable to supply blood to the brain. In all cases of both species, the lingual and facial arteries arose from the external carotid artery independently, and in a similar manner. In the lion, the other branches arose from a common trunk of two or three arteries. In the domestic cat, the occipital artery arose from the internal carotid artery in half of the cases. However, there were con siderable differences in how the carotid artery branched between the lion (large felid) and the domestic cat (small felid). (J Osaka Dent Univ 2018; 52: 149-155)
