Acclimation

In a partially collapsed underground parking lot, Drake sat leaning against the most intact wall, staring uncertainly at the gigantic cat lounging nearby. 

When it had snatched him by the collar of his shirt and carried him off, the only thing that had prevented him from flailing and screaming for help had been that same mysterious feeling that had guided his actions earlier, sending waves of security and satisfaction crashing over him, seemingly regardless of his actual situation. 

In the absence of any other viable options, Drake had decided to continue to trust it, and thus had ended up here, in the cave-like ruins of a multi-story parking garage. 

After placing him on the ground with surprising gentleness, his abductor had flopped onto its side nearly on top of him, and immediately began purring with the approximate volume and quality of a speedboat engine.

Drake had taken the opportunity to get a better look at it, and had then spent the next ten minutes trying to wrap his mind around the idea of an otherwise normal-looking housecat the size of a car. 

The cat rose suddenly to its feet, and after an affectionate head bump that left Drake sprawled across the floor, it leaped effortlessly through the partially collapsed ceiling, leaving him abruptly alone again. 

Drake rose to his feet, brushing himself off absently as he took in his surroundings more fully. 

This was near the top of the parking garage, which had to have been employee parking for one of the huge office building skyscrapers in the vicinity to have needed this many levels. The elevator was obviously not working, and the signs pointing to the stairwell lead only to a pile of rubble. 

The only way out, in the absence of any climbing gear, would have to be the same way he got in- Being carried by the scruff of his clothing like an oversized kitten.

Drake jolted, one of the most bewildering pieces of his afternoon suddenly falling into place. 

That strange feeling had compelled him to make a noise that, in retrospect, was obviously the sound of a distressed kitten, and the giant cat had responded accordingly, carrying him to a place where he would be safe from predators and purring comfortingly at him, before, if his guess was right, leaving to hunt something for him to eat.

He calmed down considerably knowing that the cat likely didn't mean him any harm, and turned his attention to the other mystery of the day. 

How had he known what to do, not only to prevent a mutated animal from killing him, but also to convince it to protect him?
