Right now, it's talk to plants in the garden for me.
Obsessive behaviors do seem to vary from household to household in my main save. I only have 4 of them turned off via tuner (2 Read Something and the 2 Browse Books). I have all packs and my bookshelves show 9 things you can turn off. There is one for butlers (I forget what pack added that) and another couple for ghosts (one of those is for pets) and a donate option that comes from Get Famous. If you only have 5 options on a bookshelf, then you must not have all packs. There was a post not too long ago where some oddball issues were caused by not having the latest version. If you have Legacy, then it should be 6.6.0.
First thing, let's make sure you are using the latest version of MCCC.Information, Guides and Announcements for the EA app.
