You may know Alpha Werecat Gumball, his most savage side which is different to his feral side beacuse it involves into a bigger and stronger body (like those typical werewolves), and a intense metabolism. I owe you an explanation about how it happens.
Well, when he go nuts due to the need of more of "something beyond paws/feet" (you know) or while he enjoy that part his body react progressively to such a level of excitement. That causes a larger and more formed body, as well as being more voracious and wild while keeping his ideas (he would not be like the typical savage who considers everyone his enemy). Basically he turns into a beast. He turns back to normal when the streak of excitement and need starts to slow down, until he feels enought exhausted for reverting his form into normal as he falls asleep having drained all his energy. It's a matter of energy and being "horny".
So yeah, in this case he took advantage while Zotty was sleeping, but that dino didn't mind in wake up. ^^;
Oh, I almost forgot, Werecat Nicole has her alpha form too, but that's for another little situation.
