A grass cat had a thick, short, buff-colored fur that easily absorbed grass pollen in the summer months, giving it an eerie and unnatural yellow-green coloration. The cat hunted by leaping upon the backs of its prey, digging its long claws into the victim's throat and neck. Even if its victim was not killed by the severing of some vital vein or nerve, it would run itself into a stupor or even to death. There had been cases of grass cats killing Men in this same manner.
