Hi & welcome to the forum

I saw you posted the same questions in another thread so I'll just be brief & say making snoring type noises in her sleep are most probably nothing to worry about.
You do need to upgrade your cage so you can give her more space & enrichment, until then don't put anything on the bars, it won't help & isn't good for them, for the time being try giving her a whimzee dog chew, the toothbrush is best, hams love them & it will help distract her from the bars.
Check out this thread for other ideas.
