Final answer:
The zygomatic gland is the salivary gland located under the eye and above the upper jaw in cats. It is different from the parotid, submandibular, and sublingual glands, which are other major salivary glands.
Step-by-step explanation:
The gland located under the eye and above the upper jaw in cats which contributes to the production of salivary glands is called the zygomatic gland. The major pairs of salivary glands in cats and other mammals include the parotid gland, the submandibular gland, and the sublingual gland. The parotid gland, which is the largest, is located in front of the ears and secretes saliva through the parotid duct near the second upper molar tooth. The submandibular gland is located beneath the lower jaw, and the sublingual gland is found underneath the tongue. However, the zygomatic gland, which is specific to the question, is situated under the eye and above the upper jaw, and is distinct from the glands mentioned in the provided context.
