Temporary play area is fine?

Background:

  • We have a Russian dwarf hamster.
  • (A) is a standard cage where our hamster normally lives, eats and sleeps.
  • (B) is where we put our hamster for a short time to play around just to change things up. Or when we are cleaning (A) and need to put him elsewhere.

Question:

  • Does (B) need bedding and/or less clutter? Or is it fine as it is since a mixed terrain for a short time can be beneficial to the hamster?
  • Not sure if other owners also have alternative/temporary play areas.
