How can I make a litter box more accessible and comfortable for arthritic cats?

To make a litter box more accessible and comfortable for arthritic cats, consider using a litter box with lower sides for easier entry, placing the litter box in a quiet and easily accessible location, providing a ramp or steps for easier access, and using softer, more comfortable litter. Additionally, ensure the litter box is kept clean and scooped regularly to prevent discomfort for the arthritic cat.
