I plan on using fleece or towels for bedding instead of paper cause I heard its healthier and less dusty and sometimes I notice my rat has sneezing episodes and I do too when I handle the bedding. I use carefresh paper. Anyways as soon as I run out of my last bag I would like to go get fleece but my boyfriend told me that rats dont like it cause they cant dig, burrow, or hide their food. Is my rat really going to get upset if he cant dig? I also wanted to use fleece cause I thought it would be easier to clean the cage and less expensive and easier to litter train. But I'll keep using paper instead if rats have the need to dig.Thanks!
