What does mog mean?
A mog is an informal word for a cat. It can sound affectionate, especially when a speaker is referring familiarly to their own pet, but it may also be used teasingly or disparagingly, particularly when describing an animal considered large, untidy, or unattractive. The word is chiefly associated with British English, although it is also understood in American English. Unlike the neutral word “cat,” “mog” gives the animal a more familiar, rough-edged, or humorous tone. Its use often suggests the speaker's attitude toward the cat more strongly than it simply identifies the species. A person might call a beloved pet “a silly mog” with evident affection, while a stranger might use the same expression critically. Although relatively uncommon in polished writing, the word remains recognizable and is especially associated with colloquial speech and humorous descriptions of household cats.
nounAn informal, sometimes affectionate or derogatory name for a cat.

"The old mog settled beside the fire and refused to move."
"That enormous mog is occupying the best chair in the room."
