Tank Toppers


(Yes, I know their water is low. I cleaned and refilled it after taking this photo.)

Tank toppers are a great way to add extra space and interest to your gerbils home, without the mess of escaped bedding that often occurs with critter trail style cages. They also allow you to mount a water bottle on a different level, and place a food dish on a different level, encouraging shy gerbils to come out into the open to eat. Toys can be hung or snapped to the bars and provide new chew and play options.

Your tank topper should be chosen with the same ideals as a wheel. It should have grid style floors to avoid tail or foot injury, and should be made solely of metal. I purchased mine from


Warnings & Tips:

Bar biting is when a gerbil obsessively gnaws on the bars of it’s cage. It can cause baldness on the nose and possible damage to the teeth. It is generally a symptom of boredom and can usually be prevented if other chew options are available. Usually. Henry (pictured above) however is a notorious bar biter no matter the toys and chews I provide. The best way to stop this bad habit is to only allow them to have their tank topper every other week. This prevents boredom and is good for their mental health.

If you are breeding your gerbils, only allow your pair to have a tank topper while there are no young present. Newborn gerbils may be placed by their mother under a ramp, where they are in danger of being crushed if you move it unknowingly. “Toddler” gerbils are clumsy and can hurt themselves falling from the highest level. Wait until your babies are of weaning age before allowing them to have access to a tank topper.

Critter Trails & Glass Walls

Critter Trail Cage

Critter Trail Cage

As a pet store employee, one of my most commonly asked questions is “which critter trail cage should I get for my new gerbils?”, and the answer is: None!

Critter trail cages, though colorful and fun, are not ideal housing for gerbils. Though perfectly fine for dwarf hamsters such as the Robo Dwarf, Chinese Dwarf, and Winter White, gerbils will likely destroy and possibly escape from a critter trail cage.

Gerbils are Chewers and Diggers:

Say goodbye to anything plastic; they will completely destroy it. Critter trail cages are primarily plastic with a wire middle. Often times gerbils will become obsessive bar biters when kept in this type of cage. As shown above, the base of a critter trail cage is fairly shallow, and you will quickly find that more bedding is out of the cage than in!

Cleanliness is Key:

Most critter trail cages have tubes and tunnels, which gerbils will often do their “business” in. This makes it difficult to keep their home clean and neat. Cleaning the tunnels requires a soak in hot soapy water and a long, flexible bottle brush.

The Alternative: 

The ideal housing for gerbils is an aquarium with a metal mesh lid. Ten gallons for two, twenty for four, and so on.

Though maybe not as visually appealing, a glass tank is simpler, easier to clean, and will provide your gerbils with a safe, happy, healthy environment.

Set up:

Bedding: Aspen and paper bedding products such as Carefresh and Kaytee’s Clean and Cozy are all acceptable bedding options for gerbils. Personally, my gerbils are kept on Kaytee’s Clean and Cozy white bedding, with a handful of Carefresh “Crinkles” for Nesting purposes. I’ve had gerbils develop allergies to both aspen and Carefresh Colors bedding in the past.

Kaytee's Clean And Cozy Bedding is a cheap and long lasting bedding with limited dust.

Line the bottom of your tank with three inches of your bedding, and then mash it down to make a dense two inch (ish) layer. This will make for a better digging experience for your gerbils. If using crinkles, add a large handful to your bedding. Your gerbils will spread it around as they “decorate” their home!

Toys & Accessories:

Wheel: There is a lot of debate among gerbil lovers as to what is the right wheel. Allow me to guide you through the wheel selection process and educate you along the way!

Option Number One: The Tail Eater

An Unsafe Wheel for Gerbils: DO NOT USE

An Unsafe Wheel for Gerbils: DO NOT USE

Though rarely seen in the market these days, this wheel with it’s bare slats has caused pain and heartache for gerbil lovers all over the world. A gerbils tail is very fragile, and can become caught between the bars causing “degloving”, a painful injury when the skin is ripped away from the bone of the tail. Never purchase this kind of wheel for your gerbil.

Option Two: The Solid Wheel


Though “safe”, this wheel does not allow waste to pass through it’s floor, your gerbil will be running in his or her own “yuck!”. Also, these kinds of wheels are usually made of plastic. Thus, they will quickly be destroyed by your gerbils teeth! This wheel can be used, but it is not ideal.

Option Three: The Flying Saucer


Similar to the solid wheel, it often becomes dirty and chewed to bits. Also, many gerbils have difficulty learning to use this wheel and it is a bit pricey, so I do not recommend it.

Option Four: The Grid Wheel


A six inch or larger grid wheel is metal, and instead of bars, it has tiny squares. Small enough that feet and tails cannot become trapped yet allowing waste to pass through. This is the ideal wheel for gerbils! It is also the cheapest and easiest to come by, it can be found at almost all pet stores as well at most Walmarts!

Home Within A Home:


Igloos are the most common hide houses for small pets, but as with all plastics, they are easily destroyed.

If you cannot acquire a ceramic hide house, I suggest this:


It is made of a wood/plastic composite. Though still plastic, is it much denser and harder to chew. It will get a little tattered around the edges, but will not likely be totally mutilated. We use this house in the pet store I work at, and it suits the gerbils well.


Again, plastic bottles will likely be chewed through, and you may come home to find a small pond in your gerbils tank! (Trust me, I know from personal experience.)

There are glass “chew proof” bottles available, but they are often hard to use in a glass tank. Currently I am using one of these:


Though plastic, it’s round design makes chewing near impossible, and it comes with a metal guard/holder that works well in a tank setup.

Last But Not Least!

Please provide chew toys for your gerbil to allow healthy chewing, as this keeps their teeth trimmed. Some good chewing toys my gerbils enjoy are pictured below.




BUT WAIT, what about food dishes?!

I didn’t forget! Though I sometimes use ceramic food dishes, they are not needed. Scatter roughly 1/8 cup of food in the tank daily and your gerbils will have lots of fun “hunting” for their food! If you are going on a weekend trip, scatter a ½ cup of food and insure the water is full, and your gerbils should be fine.

Tip: Gerbils need at least 15% protein in their diet. Most “Hamster/Gerbil” food is 13.5% or lower. Below is the food I use and love. It boasts a 17% protein content! Meal worms (dried or alive) and crickets make a great treat.
