Why Do I Use Kiln Dried Aspen Bedding?
Kiln dried aspen bedding is made from hardwood, and lacks the phenols present in softwood that causes harmful URI (Upper Respiratory Infection) in pet rats. URI can become fatal when not observed and treated very quickly.
Aspen is a safe and absorbent bedding, and much better than paper, which is non absorbent and contributes to the growth of harmful bacteria and fumes that cause URI and other health issues.
Aspen minimizes the buildup of ammonia, which helps manage odour. It also helps keep the cage more dry, and provides a comfortable bedding for pet rats.
Aspen is also pretty cost effective, and widely available. Some stores even sell lab grade aspen, which has much of the dust already removed. For other non lab grade brands, it is advised to shake out dust using a mesh bag prior to use. I personally buy Lab Grade Kiln Dried Aspen Shavings in 8 cubic foot bags from Ren's Pets Store (Canada).
As rats are fossorial mammals, meaning they need to dig and burrow as part of their behavioural necessities; bedding in the cage is an important necessity and offers enrichment as well as odor control and waste management.
Sometimes bedding can become infested with pests, especially in warehouses or stores where animals are allowed in. In order to manage this and eliminate parasites from bedding prior to use, store it in a freezer when possible, or use a preventative pest control like selamectin (aka Puppy and Kitten Revolution).
DO NOT USE CEDAR BEDDING FOR PET RATS. Even if kiln dried, cedar still contains phenols, and is harmful to their sensitive airways.
In my opinion and based on research, the best options for bedding are H**p, Kiln Dried Aspen, or Kiln Dried Pine.
I do not recommend paper as a bedding.
