i recommend getting a bonding scarf, i got mine on etsy. you pop them in then relax on the couch or something. it gives them a safe spot while still being on you, its whole purpose is to speed up the bonding process. if they want to chill inside it, great, if they want to explore, great too.
also my biggest advice is to figure out your cleaning schedule and stick to it like glue, keeping a strict cleaning regime will go a long way into keeping your squishy beans happy and healthy
amazon and esty both have good things though etsy is more expensive but nicer stuff. i'll link you some stuff in my cage

my deluxe came with the plastic ramps but I quickly took them out in favor of other methods but settled on wood ramp I'll link you. I found the ramps to be too steep and my boys kept munching on the ramp covers which are expensive to replace when you've got chewy butts
