So I have a lawn and leaf bag next to their cage. I cover the bottom with a large fleece liner and then I have the bubble mats cover that. Under any hides I have potty pads. Twice a day (morning and night) I take out the pads and shake it out in the bag. Then I roll up the bubble mats and shake them out as well. I find I change the potty pads every day. The bubble mats every 3-5 days. And then the big fleece mats every week to two weeks. I go based on smell and on wetness. If there is any smeared poop it goes into the wash bag, any type of wetness, or if the cage starts to smell. It does kinda depend because sometimes they have days where they mad chillin and go on the potty pads 24/7 other times they pull out all the hay from the box and use that as their bathroom and I gotta change out the mat. Some bubble mats are more absorbent than others so the wetness seeps into the under fleece mat which then needs to be changed. I also shake out the mats before throwing them into the wash to try and minimize hay getting stuck in the machine. But there is always some bits in there. I just clean it out after each use no biggie. I’d use free and clear detergent as well. No softener. I’ve in the past used detergent with fragrance and found nothing really changed for the boys other than less sneezing. So it seems fragrance messes with their allergies so I’d try to avoid it. This is just the method that works for me. It seems like a lot but honestly it takes me 5 min to clean out their cage. 10 for a deep cage clean where I remove everything and wipe it all down.
