If you couldn't trade with the cat then I'm inclined to believe that it was, in fact, storywise, an evil NPC and it was lying to you - manipulating you, even - the whole time for its own nefarious purposes. This was no poor cat. Nor was it nice, or your friend. You were as disposable as a diaper to it.
If the above is the case, perhaps it's not a behavioural bug to look at, so much as another pass at the dialog and what ulterior motives can be inferred from the dastardly cat's interactions.
EDIT: Of course, now, minutes later when I actually use my brain to think, I realise we're still talking about a cat. Which would explain the no-trade thing anyway. In short: egh! No idea. I can accept the possibility that a part of me just really likes the idea of a double-crossing feline enemy and this was twisting my perceptions. Miaow. (Or meow to those across the water.)
