Bin cage for hamsters on a budget

Bin cages are genuinely one of the best budget options for hamster owners — a large storage bin can give your hamster far more floor space than most pet shop cages at a fraction of the price. That said, hamster welfare needs are more demanding than starter setups suggest: they need a minimum 100x50cm footprint, at least 30cm of bedding to burrow properly, and a wheel of 28cm or more for Syrians. Before I point you toward the right supplies, can I ask — which species do you have, how old are they, and are you building from scratch or converting an existing bin?

Perfect — a 110 litre Really Useful Box is an excellent choice, the footprint is well within the right range for a Syrian. For the mesh lid you want galvanised steel weld mesh with a 1cm x 1cm grid. Anything larger and she could get her head through or chew through it quickly; plastic mesh won't hold up at all. The standard roll you want is 1m wide weld mesh cut to your lid size. For tools you'll need tin snips or strong wire cutters to cut it, and binder clips or zip ties to secure it to the lid frame once you've cut the centre panel out. A Stanley knife handles the plastic cutting cleanly.

Yes — go for the Defenders Weld Mesh Roll, 1m x 5m, 19 gauge with a 1cm x 1cm aperture. It's galvanised, rigid enough that it won't bow under its own weight, and the gauge is sturdy enough that a Syrian can't deform it through chewing. It's widely used by the hamster keeper community specifically for bin cage builds and it's well priced for the quantity you get — you'll have plenty left over. Avoid anything advertised as 'chicken wire' or hardware cloth with larger holes; they're either too flexible or the gaps are too wide.

The cleanest method is to cut the centre panel out of the plastic lid, leaving a border of about 3–4cm all the way around. Cut your mesh slightly larger than the hole, lay it on top of the border, and secure it with metal binder clips around the edges — they grip the plastic rim and the mesh firmly without any tools. Some people also use zip ties through small drilled holes for a more permanent fix. Run your fingers across every cut edge of the mesh before fitting it and use pliers to fold over any sharp wire ends so there's nothing that could catch her.

Three things worth sorting before she moves in: bedding depth is the big one — fill it to at least 30cm with a paper-based substrate like Carefresh or hemp bedding so she can actually burrow. Get a 28cm or larger wheel; the Niteangel or Wodent Wheel are the go-to choices and worth the spend. And make sure there's no way she can push the lid off — binder clips on the lid itself, not just the mesh, will hold it shut. Once those are in place you'll have a setup that genuinely meets her needs and cost you very little.
