I'm able to rat sit one to three rats, at this time speutered ones only as I've got an intact male but this will change in time.
(I will consider more depending on circumstances)
I do not drive, however so can't do any pick ups or drop offs. I require that the rats owner leave contact info, money for a cab to the vet in case of an emergency (if they aren't available to do it) or provide the name/contact number of a person willing to transport a sick/injured rat. For planned vacations and people leaving the immediate area, I do ask $10 per day and the rats' food etc must be provided.
I will also be available to do QT after my boyz pass, as I'm taking a break from personal rats til I have a vet fund built up.
ETA: might help if i said where I am, eh? Southern NH, Manchester to be exact.
