Explanation:
Wood, plastic, and rubber. The crate needs strong materials in order to contain the animal. Wood is the most cost effective, but padding is required to prevent the animal from getting hurt. Plastic is also ideal, very strong and is very easy to manipulate and manufacture for any need. Rubber is the most comfortable, and can cushion the animal to prevent injury. Rubber can be cut, so it is best to use it for smaller and more docile animals.
