Hi. I'm Jun , I live in Florida ,and I have 12 Degus. ( 3 baby boys up for adoption, no fees, BTW)
I was wondering if you use vinegar only to clean the cage with? I use straight Distilled white vinegar. What I do is, I soak all their stuff up with it, leave it for about 10 minutes and rinse it clean and air dry, and wipe with coffee filters because it leaves no lint and it is only a $1 for 200ct.
Also, I was wondering what type of Dust bath do you use? Some dust baths are not good in quality. we went through several and found gound pumice and white ash mix.
Also, we use chincilla pellets only because they seem to have more vitamin C. We supplment with Vitamin C in their water once a week. I just dissolve one tablet of Vitamin C in their water bottle.
Also , I use the paper litter, wich has small amounts of dust and use alot of Timothy hay with it to control odors and so they can dig and hide food ( they like to do that in the winter for some reason)and eat also.
Sorry to jump in but I wanted to help.
I hope I didn't step on anyone's toes.
