MISSING:
Day 12 gacha pup (willing to pay C$), and missing Earth Day butterfly wolf.
HAVE:
All pets in my Overflow folder!
(I've taken to naming the monthly pets by the day they most recently grew, followed by the CS time I adopted them. If I am missing adoption times, it's because it was an extra that someone else gave to me. It's unknown whether there will be split growths for some of them. Event pets have regular names.)
