This question already has an answer here:
There's a great early SciFi book by George R R Martin called "Tuf Voyaging". In one of the chapters he uses his spaceship "Seed Ship" to create a bunch of alien monsters for a planet that fights it wars through monster arena battles.
He create a large cat like creature called a "cobalcat", it has infared eyes, and psionic abilities.
Has this cat creature turned up in any of his other short stories?
I'm sure I can remember a story about a human manned spaceship that crashes? or lands on an alien planet. While there they come across one of these cats that tricks them into thinking its harmless and benign. But eventually kills them once they take off with it on the ship? I think thats how it goes. I'm a bit murky on the details. Any help would be great. Thanks.
