The option to read to my pet is missing (and I haven't already read it).

I guess it is not a book, Subetalodge does not list it as such. (Thankfully they are running again, I wasted 1kCredits for a "book", that turned out to be no book after all, because I couldn't check there and it was the last day of December :( )

Aha, ok. At the time I posted this it was listed as a book on Subetalodge. Now I see that has changed. Thanks. :)
