With my four, I ended up not waiting... largely due to that was the only way I could check them after thier long journey to me. I figured since I already handled them quite a bit to check them out, might as well start the bonding
progress. I ended up with some issues after a 'honeymoon period' (several weeks) that made be believe I needed to step back & allow them to normalize before continuing. It worked & we were able to continue our journey together much smoother.
In other words, I would advise at least a day or two to lets them get use to the new sights & sounds
of your home. Don't ignore them by any means; walk by, talk to them, just give let them realize their new home is safe. That said, if you're already started the bonding
, maybe just give them a day to get over the change.
