The term "Spider cat" has not been confirmed by official sources.
In 100 AG, Team Avatar visited Wan Shi Tong's Library searching for information on the Fire Nation. When they first arrived, they saw the spider cat's head hanging on display on one of the pillars of the building.
The spider cat has the head of a spider and the ears of a cat. It has a total of six red compound eyes, two large and four small. The spider cat's head is covered in short brown and gray fur. The creature itself is large enough that its head is comparable in size to that of a walrus yak.
