Grabbed it, thanks!
Oh boy, oh boy! I've bred my first 5th gen Z!!! Mama was my first 4th, born at the start of last October! So getting a fifth didn't take long...not! Papa was born in the middle of April, and this is their ninth offspring. i recently bred one more fourth gen, but who knows when I'll get another, so a mate for this 5th gen seems a long way off. I do have a pair of 4th gen z'pygmies, though--so fingers crossed!
ETA: just bred fourth gen #4, so maybe a mate for this baby will come along before too long...
