Have you thought about it possibly being Tiger's way of trying to communicate to you that he is constipated? My cat acts differently (energy,vocals, litterbox use etc) when he gets that way. She my be in pain and attempting to ask for help by getting your attention that way.
I hope you get things figured out and that Tiger feels better soon
