I have been on a nostalgia trip recently. I've been looking at test modes for some toys. I wondered if there was one for the #iCat, and found one. Sterling Andrews on YouTube demonstrated it, and hearing the sounds and seeing the iCat again brought it all back to me.
I still have my white iCat all these years later. It still works, and it cleaned up pretty well! It's just slightly yellowed, or "sun-kissed" as I like to say.
