This is a specific conversation about Hamster supplies — what hamsters actually need — ask about yours and get one honest answer for your exact situation.

Your vet has flagged something really important — burrowing isn't optional enrichment for Syrian hamsters, it's a core welfare need, and a stressed hamster is often one that simply can't dig properly. Most cages sold in pet shops allow maybe 5–10cm of substrate, which is nowhere near enough. Syrians in the wild create burrow systems up to a metre deep, and even in captivity they need at least 30–40cm to exhibit natural behaviour and feel secure. Before I point you toward the right substrate, can I ask: what size is your hamster's enclosure right now, and what bedding are you currently using?
He's in a 100x50cm tank which I think is decent, but I'm only using about 10cm of the standard wood shavings from the pet shop. The vet said he's been bar-chewing and she thinks it's stress from not being able to burrow properly.

The tank size is actually great — that's one of the best enclosure choices you can make. The problem is almost certainly the substrate depth. Ten centimetres with wood shavings won't hold a tunnel at all; it just collapses. Your Syrian needs a substrate that compacts well and holds burrow structure at a depth of at least 30cm, ideally more. Bar-chewing is a classic sign of frustration and under-stimulation, and inadequate burrowing opportunity is one of the most common causes. What substrate mix are you open to — purely paper-based, or are you happy to layer different materials?
I'm open to anything that actually works. I didn't realise the depth mattered that much — I thought it was mainly about cleanliness.

Completely understandable — most pet shop advice focuses on hygiene rather than behaviour. For a Syrian who needs to burrow properly, my clear recommendation is Carefresh Natural unbleached paper bedding. It's soft enough to be comfortable, compacts brilliantly so tunnels hold their shape, and it's dust-extracted which matters for respiratory health. For your 100x50cm tank, fill it to at least 30cm — 40cm if you can manage it. You'll need a large bag; the 60-litre size is the most economical for this purpose. Some keepers add a layer of coconut fibre or plain topsoil at the base to give it extra structural integrity, but Carefresh alone at that depth makes a significant difference. You should see the bar-chewing reduce within a week or two once he can actually construct a proper burrow system.
That sounds straightforward. Is the 60-litre bag available on Amazon? And how often would I need to replace all of it?
inparticular.ai
Yes — Carefresh Natural 60L is listed on Amazon UK and is usually available on Subscribe & Save which brings the cost down noticeably. On full replacement: with a deep setup you don't need to change everything frequently. Spot-clean the surface toilet corner every few days, and do a full substrate change every four to six weeks depending on how much he uses one area consistently. Deep substrate actually stays fresher longer because the ammonia disperses through a greater volume. The key is not disturbing his burrow network unnecessarily — if he's built tunnels, try to preserve them during spot cleans. That continuity is part of what makes him feel secure.
Really helpful, thank you. I had no idea I was underselling the bedding so much. I'll order the 60L bag today.

It makes a bigger difference than almost any other single change you can make for a Syrian. Once he's got 35–40cm of Carefresh to work with, you'll likely see him digging within hours of the refresh — it's genuinely satisfying to watch. If the bar-chewing continues after a couple of weeks even with the deeper substrate, it's worth going back to your vet just to rule out anything else, but the vast majority of cases resolve with this fix. Good luck with him.
