Once they get older, cats may have some difficulty getting into their litter box. This is especially true if the box has high sides. Fortunately, some companies make boxes that are low on one side, letting your cat step in without as much effort. Another option would be to use a small ramp of some kind, but I am not aware of this type of product being available. If you are handy however, you could build one yourself.
