Hutches are a type of furniture that is typically used to house small animals, such as rabbits or guinea pigs. The term 'hutches' can also refer to the wooden cages that are used to contain these animals. COOPS, which are five letters long, are similar to hutches in that they are also used to house animals, but they are usually larger and made of metal or wire. PENS, which are four letters long, are also used to contain animals, but they are usually smaller than COOPS and made of wood. Pins, which are also four letters long, are used to secure hutches and COOPS together, ensuring that the animals remain safely contained.
