*spoiler, slightly*
you get the sapphire pin after beating the wind elemental as thanks from the merchants whos stalls were in its path of destruction.

i actually sent the guys a AGDI an email suggesting this but they never got back to me, a remake of qfg4 would be nice, it runs buggy at best on modern systems even with dos box, so really having it retooled would help alot of fans play it.

The answer to your query comes in qfg5, the musical katta is described as a 'kitten' by her parents, despite looking to be not much smaller then they are...my guess, katta grow much faster then humans, so alot of the katta wandering around shapier may very well still be kittens.
