What is a Topper?

A tank topper is simply a second level in your tank, often made from the wire-top part of an old cage. This is a zone entirely separate from their burrowing and nesting area: a chill-out pad where Gerbils can enjoy a sand bath, run on the wheel and eat. There are plenty of unsuitable cages for rodents on second-hand selling sites and many we discuss in our Housing page, the top wire part, however, can be very handy to make a topper. We DIY’ed an old aquarium and added a topper in the pictures above.

Lids & frames for your topper

You can DIY this yourself, and remember any wood you use needs to be natural, free from dyes, preservatives and untreated. Safer construction woods for Gerbils are Spruce, Poplar, Aspen, Birch. Or you can order with your dimensions from;

To access the tank and hold the topper in place, you will need a lid for one section of the tank and a wooden frame/topper support to hold the topper in place, in the other section. You need a topper that is at least 4cm narrower than the width of your tank, to allow for the width of the wood used to make the wooden topper support frame. The lid is a wooden frame with mouse wire. The topper support is simply the wooden frame.

Tanks with a flat glass lip: If you have a tank with a flat glass lip which a frame/lid can rest on, you can construct both lid and frame to rest on the glass lip as in both pictured below.

Tanks without a flat glass lip: You will need to construct the lid a little differently. We’ve used an Ikea Detolf as an example so you can see how the lids rest on the glass edge. Although this example does not have a topper, you would create the topper frame in the same way just minus the mouse wire. Tutorials are found online available, as are suppliers that will make these to order HappyHenrysHomes – Lids and Toppers & Kirsty’s Tank Tops

Topper Accessories

You’ll need to attach wooden ledges. A simple willow stick bridge allows access up and down Hanging Bridge You can attach the bridge with metal hooks in the wooden platform. You can then add your water bottles, sand bath, food etc. Top Tip: Cover your wooden ledges with thin card or cardboard to keep the wood fresh and for easy cleaning.
