This master thesis addresses the issues regarding keeping cats in shelters with a focus on developing a better caging system for shelter use. The focus areas are divided between three main actors; The shelter, the cats and the customers. Though visits at Danish cat shelters research is done defining problematic areas like hygiene, space limitations, lack of stimulation of the cats and an unfriendly environment for the customers. The customers are a very important factor of this project since that is the areas where the current solutions come in short. On this front, the interaction with the cages is thoroughly investigated as well as the way the customer meets the cant when entering the room. Another factor is the cat’s health which is improved through accessible options for exercise and incorporated stimulation of the instincts. Lastly the shelters needs are approached through installing simple solutions to replace all of the homemade initiatives placed in shelters.
