Laanur

The laanur was an animal native to the planet Mestiko, with a feline body, dark eyes, webbed back feet, prehensile forefeet and lustrous fur striped blue and silver. Prior to 2265, the laanur was a popular domesticated pet among the Payav people of Mestiko. Following the ecological disaster of "the Pulse", however, the species was all but wiped out. The Payav attempted to recreate laanurs with stored DNA, but the resulting creatures proved vicious and untamable. (TOS eBook: Mere Anarchy: Its Hour Come Round)
