Echo and Tally are welcoming new additions Toby and Lucy on Saturday.  They
are being given to us by a coworker who feels her son does not care for
them well.  Our vet has told us that we need to keep the two groups
separated for a while, but what else should we be doing?  And when can we
start introducing them to each other.  Echo and Tally have been together
since birth (they are turning four) and so have Toby and Lucy (they are
two).  Any suggestions would be appreciated.
