Day 4... when to let them out a bit?

[MedusaIsHavingaBadHairday]

This will be the 4th proper day of babies. They are confident in their two rooms and getting very friendly :)

How long do I keep them up here? Portia saw them briefly this morning through the gate and had a quick hiss ( ) then stalked off. Oddly they just looked at her back and weren't unduly worried, but I don't want her leaving home in a huff! I am tempted to let them have a wander when she is out then put them back upstairs when she is in.
I think it's safe to say she isn't thrilled at her first sighting, but I didn't expect her to be..however I am not sure how is best to proceed for all!1§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§

^that was Obi's contribution to the conversation btw

Any tips gratefully received!!

For a quick moment, I thought you meant outside the house.

You're aching to try to normalize things, aren't you? Just aching.

See I never bothered with the while separating them thing when we got new rescues, I couldn't because DS whirlwinds around every room constantly. They had a hiss, worked out who was boss. Then got on with things.
