Frankly, when Jon awoke next he was expecting more than he got.
He did, indeed have a tail now, and his ears which had before been just a bit pointed and higher up on his head were now closer to being above his eyes and at the top of his head, they were also starting to grow fur and were well on their way to gaining the appearance of full-on cats ears.
It looked like his fur pattern was going to be that of a random street cat, namely differing shades of gray in a striped pattern, with deeper black lines going up the top of his tail and the... er, corners of his ears, for lack of better term.
For only a moment he wondered if that was all the cat features he would gain, but it also looked as though he apparently had elongated, pointed fingernails that seemed on their way to being retractable, and there was some rather thick hair growing on his lower shins down to his toes, which seemed slightly longer for some reason aside from the sharper nails.
A quick inspection by his tongue determined that his canines were now closer to being felines, and if he judged it right his tongue was rougher too.
His bathrobe was also sticking to him, and the expected bulges in expected places told him that he had continued to develop towards the female form whilst he had been sleeping, and was likely now more female than male. He supposed that this was a good reason to start thinking of himself as a girl, but he'd come to that hurdle later, for now he was finished with his self-inspection and with his pounding headache, he could be in denial later, for now he needed to get back to sleep. He didn't even notice his mother come in to check on him.
