Tusk cats were large feline predators with a large pair of distinct tusks growing from their lower jaws. This put them at morphological odds with many tusked animals which often featured tusks growing from the upper jaw. A second, less-noticeable pair of tusk-like fleshy appendages grew from their cheekbones. Tusk cats were covered in fur that could range from browns to grays to almost red, and gray ones had faint spotted patterns. They seemed to share some features with ungulates, with swift galloping gaits and toes ending in hoof-like appendages. Some smaller subspecies featured more claw-like digits as well as variations on the number of tusk-like facial wattles. Their tails were long and muscular to balance them as they ran, ending in a leaf-shaped spur. They were known for keen eyesight and a sharp sense of smell. They appeared similar to the larger Naboo predator known as the narglatch.
Tusk cats were carnivorous and preyed upon smaller animals native to Naboo. Natural shepherds, they mated for life and instinctively formed prides to guard herds of Shaak, killing one to eat every seven or eight days. Their tusks were used as both offensive hunting weapons as well as for defense. Though they were aggressive predators, as cubs they could easily be domesticated and even ridden, but could also adapt back to the wild if released.
Despite their predatory nature, tusk cats could be tamed for a variety of uses, notably as mounts. Domesticated tusk cats were said to be naturally protective and gentle towards Naboo children. Tusk cat riders were employed as shepherds for various livestock, including shaak and the royal Gualama herd. Tusk cats also served as military patrol vehicles for the Naboo military, recreational attractions, police work, and ceremonial beasts with royalty. When outfitting a tusk cat mount, the traditional bridle was abandoned in favor of a harness attached to the tusks. During the Victory Races of Naboo, Queen Padmé Amidala herself rode a tusk cat. The tusks of dead tusk cats were typically carved into memorial cups and displayed.
Tusk cats were among many creatures moved off-planet as pets following The Battle of Naboo due to the growing demand for Naboo pets among spacers.
