P.S and thereby hangs a tail

Being a cat person curiosity finally got the better of me today and I buzzed that buzzer. A lady answered and she confirmed that it was her cat and I explained how Molly plays and then brings him home every day at mealtimes and could she pleeeease tell me what is his name? It's Toby, she said and I don't mind you feeding him at all. So we were right , it was a female owner and she is out all day and he is a boy . Mystery finally solved. However, after all that investigation ,he doesn't answer to Toby any more than he answered to Tailor.
