So as the collection has grown my wife is less and less a fan of keeping live rats (we're not fans lol) so I've been trying the transition to frozen. Today I'm 5/5 including my big female Mojave who has NEVER in her life taken frozen (she just smashed a 102g frozen rat!!) Hopefully we'll go 6/6 here! Very quick and convenient. Haven't even done the zombie dance! Thawed, heat up the head with a hair dryer stick the head in the opening of the hide and walk away! Pretty ecstatic right now!
