The major salivary glands in the cat include the parotid, zygomatic, mandibular, and sublingual. The mandibular salivary gland is located caudal to the ramus of the mandible and ventral to the parotid gland. The sublingual salivary gland lies in close approximation to the rostral aspect of the mandibular gland.

Saliva from the parotid gland exits at a papilla in the alveolar mucosa, just caudal to the maxillary fourth premolar. Saliva from the zygomatic gland exits at a papilla in the alveolar mucosa near the maxillary first molar. Saliva from the mandibular and sublingual glands enters the oral cavity through the sublingual caruncles located ventral and rostral to the base of the tongue (Figure 1.4) (Illustration 1.1).

Cats have four molar salivary glands. The buccal molar glands empty into the oral cavity through several small ducts. The lingual molar glands are located in the membranous molar pad linguodistal to the mandibular first molar teeth (Figure 1.5).
