What to fill a rat’s burrow with? - in detail
A suitable substrate for a rodent’s tunnel system should be absorbent, non‑abrasive, and free of strong odors. Soft wood shavings such as aspen or pine (without aromatic oils) provide a comfortable base and aid in moisture control. Paper‑based products—shredded newspaper, plain tissue, or recycled paper bedding—offer similar absorbency and are easy to replace.
Nest‑building material must be pliable and safe for chewing. Untreated cotton fibers, fleece strips, or plain hemp can be torn into nests without introducing toxins. Small amounts of dried grass or hay add texture and encourage natural behavior.
Food and water sources should be positioned at the tunnel entrance to prevent spillage inside the burrow. A shallow water dish with a stainless‑steel edge reduces the risk of contamination, while a dry feed container prevents moisture buildup.
Enrichment items enhance mental stimulation. Plastic tunnels, chew sticks, or wooden blocks can be placed within the network, provided they are free of paint, varnish, or metal components.
Maintenance considerations include regular substrate replacement to avoid ammonia buildup, weekly cleaning of feeding and watering stations, and periodic inspection for mold or pest infestation. Avoid cedar, scented oils, and any material that may cause respiratory irritation.
In summary, an optimal fill consists of:
