The main criterion when choosing the right rat cage is size, because the animals are curious, like to climb and are very active. The ideal housing therefore has several floors, so that the animals can enjoy sufficient space and relaxation. Wooden rat cages are suitable for indoor and outdoor use. The laminated wood does not absorb odours or moisture and is made from natural material all around. But many rats like to nibble everything they can get their teeth on. For very nibbly animals, therefore, metal rat cages are the better choice. A metal rat cage is also easy to clean. Often, however, immense boredom leads to compensatory activities such as constant gnawing. So that such boredom doesn’t even start, the rat cage should be properly equipped.
