I'm not entirely sure this will help, as I haven't tried adopting a pet. I usually turn off pets in the game options. And at the moment don't have Pets installed.
However, when I searched on this problem Nraas Overwatch came up. So I gave it a read and it looks like it might help with those notices? I'm not for sure, but it might be worth looking into.
