Yeah... when I first saw Makoto's site's image, I hadn't obtained Etranger yet. So, simply put, the image mentally blurred into making me think I had seen "someone" holding the cat, as in, someone not related to the EH creation cast.
As such, I am now 100% sure, until evidence of otherwise surfaces, that this plush has only one in existance and it was toyed with by the creation crew. Hell, maybe one of them even crafted it. I'll bet you Etranger holds the answers.
He resurfaces again...
Actually, according to Hitoshi Doi, during the run of the late-night El-Hazard Radio Show, Tetsuya and Etsuko (Makoto and Alielle) talked about how the dolls were on sale.

Oh well, all a devoted fan can do is keep an eye out and hope one day that one of those plushies shows up on this side, be it eBay or some dealer or whatever...
And on that day, I'm sure there will be much bloodshed as prolly 4-8 people scramble to outbid/buy it before anyone else...
I have a custom Ura vest though that a cosplaying friend sold to me when he was done with it. (Actually, it came it handy during winter cons because that thing was warm and comfortable as hell.) (it also made Kazuto Nakazawa do a double take which was priceless.)
I'm glad to see that people do visit my page...
