Paper towels??

[Sahara]

I saw a tiktok the other day about a woman who had a fairly large cage. In most of the cage, she had proper bedding. In a small part of the cage, she laid paper towels flat to set things like the sand bath and food dish on. I’m assuming she did this for easier cleanup. The paper towels were not shredded and there was no other bedding in this specific area of the cage... just paper towels laid down flat. I thought it was a good idea to help keep my hamsters food dish and sand bath cleaner and free of a ton of bedding. Is it ok to have a small section of the cage with just paper towels and no bedding if the rest of the cage has plenty of bedding?
