Put A Lid On It—An
Aquarium That Is

Supplies

• A roll or piece of ½ by ½ hardware wire mesh
• Needle nose pliers
• Clippers capable of cutting the wire
• Optional - metal file, duct tape, or an electric grinder

Be it at a garage sale, thrift shop, or swap meet, most of us will jump at the chance to buy a used aquarium for a very low price. These great potential rat and mouse homes often cost $2 or less for a 5 gallon, and great deals can be had on larger ones as well. Unfortunately, most of these either do not have a lid, or they come with glass lids unsuitable for use with anything but fish. This is where those “great deals” can quickly become expensive investments. Screen lids from a pet shop start at $10, and they do not allow much air exchange. The cheapest (and best) lids are ones you can make yourself.

The No Frills, Low Cost, Little Effort Rat Or Mouse House Lid

Step One

Unroll a section of the wire mesh and flatten it out. Center it on top of your tank so that there is a 3 square overhang on all sides (4 square for anything larger than a 5 gallon). Trim off excess so that all four sides are flush and no points (prongs) stick out.

Step Two
While holding the wire centered on top of the tank, gently fold down one long side of the overhanging wire (fold A). Use the top lip of the aquarium to fold against so that you get a tight, sharp edge. Repeat this on the other long side. This should give you a snug fit with overhangs at both short ends.

Figure 1.

Step Three
Cut along each end as shown in figure 1 (cut A). Leave prongs attached to the folded long side. Cut so that the prongs are as long as possible.

Step Four
Make the second cut (cut B) on each unfolded short end. This cut should be flush with no prongs left behind.

Step Five

Bend down the overhanging short end pieces using the aquarium edge to make the bend straight and tight.
 
Step Six

Figure 2.

Use needle nose pliers and bend the prongs from the long sides around the flush cut edge of the short end (Figure 2). This attaches the edges of the lid together. Be careful not to do this too tightly or you will not be able to lift the lid.

This is your finished lid. For mice nothing else need be done. For rats (or hamsters) you must add a heavy weight like a brick or large book to keep them from pushing the lid open.

Step Seven (optional)
The edges of this lid will be left with sharp bumps. If you are careful you can use the lid this way without problems. I always end up getting scratched or my clothes snagged, so I get rid of these bumps. One easy way to do this is to take a metal file and whisk away anything sharp. I have an electric grinder which works wonders at doing the same thing. You can also take duct tape and run it along the inside of the edge of the wire. Leave enough hanging off the bottom to fold over sandwiching the sharp points between the halves. This will need to be replaced periodically as it wears out.

Making A Play Pen For Your Rats

Needs A More Interesting Play/ Exercise Area For Rats
Victoria Coverley, age 15, England
Q  As a rat and mouse enthusiast, and as I currently own two female rats, I am writing to you for any information that you may have on how to provide a more interesting play/exercise area for them. At the moment, they have an adequately sized tank with a wheel and other play things and are also allowed to roam around my bedroom. As I also own many other animals as well, including a dog, it is obviously not always practical for them to be out of their cage for extended amounts of time. I do, however, wish to make their cage more interesting and perhaps build them a play area with rope ladders, etc., to amuse them.

A  There are a great number of things you can do to create a wonderful play area for your rats. Many people like to add lots of toys to their rats’ cages, while others prefer to build them their own play area that they can use part of the day outside their cage. Both are wonderful ideas.

There are lots of toys and fun things that can be added to your rats’ cage. The only thing limiting you is space. Though rats enjoy all the toys, they do require a certain amount of open space as well. Your choice of toys will be limited in number and size to what fits in the cage.

Some of the best toys for inside cages are tubes, wheels, boxes, and balls. PVC tubes can be purchased at hardware stores and are very inexpensive. They come in many different sections including curves, Ys, and Ts, as well as straight sections. These are durable, easy to clean, and the rats love them. Colorful plastic tubes the correct size for rats can also be found in many pet shops (try looking in the ferret section of your local store). You can also use large cardboard tubes (the kind carpet or large rolls of paper come on—just cut to size).

Rats even enjoy simple things like this cup. Photo by Karen Robbins.

Wheels are one of my own favorite “in cage” toys for rats. When raised with wheels from the time they are young, most rats (even the mellow couch potato boys) will use those wheels throughout their lives. In the wild, rats move and run constantly, something our caged friends often do not have the opportunity to do. Having access to a wheel allows for this kind of activity. The biggest problem with wheels is their size. Adult rats require a minimum of an 11" wheel. Many cages are not designed for a wheel this height, and often such a large object would simply take up too much of the rats’ living space inside its cage.

Boxes are of course an eternal favorite with rats. They sleep in them, on them, play hide and seek in them, and enjoy them thoroughly. There are many options for boxes, from those that are made of plastic and wood, to the simple cardboard box. Rats enjoy permanent boxes, but keep in mind they always have to be kept clean. Rats just aren’t always the best of housekeepers. My own favorites are cardboard boxes (my rats love the kind that a 12 pack of soda comes in). Not only do the rats get all the benefits of having a cardboard box, but they also get to destroy it! What fun! Then, when the box is soiled or chewed to pieces, I simply throw it away.

Balls and small carry toys are enjoyed by some rats and not by others. Small plastic balls are sold for ferrets that are designed to hold food. Stuff them with small pieces of fruit or other food and rats will roll them around for a long time to get that food out. Often the rats will push and carry those balls even when there is no food in them. Some small plastic toys made for cats are also loved by many rats just as something to move around their cage.

Many people are not satisfied with what will fit inside their rats’ cage. Either their rats cage is too small for the largest of the toys, or they simply like for their rats to be able to get out and play in a larger area. This is a great idea, and can be used in several different ways depending on the person’s need. Some people have a number of rats and they like to reserve one very large cage or aquarium for use as the “play ground.” This is a secure area, and their rats can be rotated into it throughout the day. People having fewer rats often find that they want to interact with and enjoy their rats while they are in the playground. Because they have some supervision, this allows the playground to be less secure. Often, people will simply designate the top of a table for the purpose. Most rats will not make much of an attempt to get down from a table, though I would recommend supervision until you know for sure how your rat will react.

With this much space you can really let your imagination go wild. The same toys that are good in cages work beautifully in a playground, as do many other things. Mazes can be made out of PVC pipe, with long, short, curving, and crossing tunnels. Wooden towers complete with ladders can be built, and bridges made out of heavy rope. Some rats love hammocks and swings, while others prefer to remain grounded. A visit to a toy store may provide many fantastic toys to make your rats’ playpen even more like Disneyland, and you may even find the same toys (slightly used) at the local thrift shop for a lot less money.

For the most part, your rat will probably love just about any toy you give them. With a little common sense, a fantastic play area can be made. Rats are like young kids, if they can get it in their mouths or cut themselves on it . . . they will. They also will be entertained for hours by something as simple as a cardboard box. Just think how excited they will get when you design a rat version of Disneyland for them.
