With 3 cats, we change ours every few days but sometimes it doesn't need to be changed every few days. Usually our oldest cat will tell us when it needs to be tended to by leaving presents at the front door ahem lol. It really all depends on the cats...but yeah leaving them unattended for very long periods of time without any food or cleaning I consider that abusive.I think it also depends on what kind of litter you have too. I should probably tell my friend to clean it everyday while he's taking care of them.
