Some rat cages and accessories are made from wire. While this material isn’t inherently dangerous for your rats, did you know there are some things you should be aware of?
First, if too much of the walking area of the cage is made from wire, your rats may be susceptible to a painful condition known as “bumblefoot”, where their feet become infected and swollen. Second, if the spacing of the wire is too far apart, it’s possible for your rats’ legs to slip and get stuck between the wires, leading to broken legs or feet.
Both of these concerns are easily preventable by covering some of the wire walking areas with a sturdy material (and all areas where wire spacing is a concern).
