In Vic we have to sign them over then the other person has to hold them for 6 months before they are able to sign them back, this basically gives them ownership of sorts, IMO I think this is STUPID it is supposed to be about the welfare of the animal, we have no such thing as breeding loans here either, the only exception is if your vet will care for them whilst you are away as they are excempt from Licences but can be expensive.
This time of year is not bad though as most of us are starting to cool anyway so brumation is the ideal, or for those of us in Vic the only legal way.
