Adults are distinctive by their medium body size, varying shades of purple-blue skin, and numerous warts that cover the body. These warts increase in size as they near the top of the large, paddle-like tail. Young frogcats, or frogkits, are bright yellow in color. Frogcats also have loose and wrinkled skin as a natural adaptation against predators. The frogcat has four eyes, two of which are smaller than the others.
Frogkits develop rapidly, resembling adults by 3 months of age and becoming reproductively viable by 8-12 months of age. When they are adults, their lifespan is short and often ends due to a predator or disease.
Frogcats strictly live in riparian habitats. They occupy seasonal river beds or ravines, and build complex communal mounds for kin rearing. They prefer mixed aquatic and terrestrial territory with ample cover, such as vegetation and cliff faces.
Frogcats are primarily herbivores, consuming fruits and foliage of lyracs. Juveniles consume seeds that are chewed into a fine paste by the parents.
Frogcats breed by sexual reproduction, with males and females pairing up for a few consecutive days to mate. Although males are possessive and usually will guard their one selected female for the season, females practice polyandry, and will often mate with multiple males in order to increase the genetic diversity of their offspring. Gestation is about four weeks and frogcats will often have many fathers for one litter.
Frogcats have incredible eyesight, having at least 9 types of photoreceptors, compared to the 3-5 types typical for most creatures.
