Loki listened to Pucks' explanation, then gave a sly smile. It wasn't that difficult, just took a little bit more concentration as his eyes glowed green for a moment. Soon enough he had black cat ears amidst his hair; a very partial transformation rather than a full shape-shift.

Pulling back enough for Puck to see them, even if it meant no cuddles for the moment. Smirking too, before chuckling and then his eyes were glowing green once more. This time for a full shape-shift, of a dark colored large cat with long fur. Not so large at the big cats of Africa or Asia, but larger than a house-cat. The long fur being part of the breed, as it was suited for a winter climate.

Only then did Loki turn blue-green eyes up to Puck, and crawl back in to cuddle against him.
