When he's bored he tends to play with it more, so I looked up things to buy for people with Alzheimer's when they do get bored, hoping it would help, but hasn't. He doesn't understand why it's there even though I explain it to him Over and Over and know he's forgotten everything I said. I don't know what else to do and I get tired of cleaning up poop. Has anyone ever had this problem and if so please tell me what I can do.
