hi =) i think the next step would be the rabies shot......but your vet should inform you of all the required and recommended shots (lepto shot 1&2 is recommended if you live in a wooded or surburb area)
it is recommended to neuteured at 6 months, or right before their first heat or.....darn what do guys get...(sorry, i have two girls)
anyway; hope everything goes as planned
