Is Teacup size rare?

[Tad Carlucci]

While most traits are breedable, size is not.

Size is random.

While KittyCatS has never published the odds, the players have worked them out, at least roughly. As I recall, the odds of a Tea Cup are fairly low, but not the lowest (I believe that would be Mega Puss). For more, there is an old thread in the Breeding forum (IIRC) which has the odds as we worked them out.
