From 2009 to 2013 you can find the staff litter in November, under dog in the search filter.
After 2013, this litter was moved to a release date in September. So you can find each litter of staff pups in September from 2014 to our latest, 2018.

Additionally, the GHs have made their own similar litter of cats for the past few years. You can find them in June, starting in 2016 and continuing right up to this very month in 2019! Not all the cats have finished growing yet but a few have. c:
