The blood vessels of the anal sac in the domestic cat--A. rectalis caudalis and A. perinealis ventralis, from which the former arises--are visceral blood vessels. A rectalis caudalis, being the origin of anal sac arteries, facilitates the blood supply of the anal sac, while the duct of the anal sac is vascularized mainly by branches from the A. perinealis ventralis. Within the anal sac wall, the anal sac arteries ramify to become Rr. glandulae holocrinae, Rr. glandulae apocrinae as well as branches of a vascular network in the mucosal propria from which Rr. epitheliales arise. All of the mentioned rami extend into a close-meshed capillary network. The venous drainage is facilitated by veins that run mainly parallel to the arterial blood vessels.
家猫肛门囊的血管——直肠尾动脉和会阴腹侧动脉（前者由此发出）是内脏血管。直肠尾动脉作为肛门囊动脉的起源，为肛门囊提供血液供应，而肛门囊导管主要由会阴腹侧动脉的分支供血。在肛门囊壁内，肛门囊动脉分支形成全分泌腺支、顶浆分泌腺支以及黏膜固有层血管网的分支，上皮支由此发出。所有上述分支都延伸至紧密交织的毛细血管网。静脉引流主要由与动脉血管大致平行的静脉来完成。
