So the Gemini pet thing has been going on for a while now. And I just kind of did research into it all and learned more than I ever cared to about Zodiac or Astrology.
With that being said, I want to bring up this discussion point to see if anyone knows.
The pets are based on the symbols/signs.
Gemini sign or symbol is twins. So the pet was a lizard with 2 heads and 2 tails.
The Cancer pet is next. In item preview, it shows it as a crab/lobster looking thing, which matches its symbol.
So the symbols are this:
Aries - Ram
Taurus - Bull
Gemini - Twins
Cancer - Crab
Leo - Lion
Virgo - Maiden (virgin)*
Scorpio - Scorpion
Sagittarius - Archer*
Capricorn - Goat
Aquarius - Water-bearer*
Pisces - Fishes*
I put an asterisk next to the ones that I think aren't self-explanatory.
