Translation of Katzenfutter

It looks like we need to invite Erika again to my home, once the cake is ready. Of course, this should be done before Sunday to stay in the chocolate cake race. We should buy cream too.
Thanks a lot. My wife, daughter and I came back with a flu from the Swiss mountains, but now we are getting better. How are you? 'Vos' is only used in antique Spanish as 'usted', in the singular form of course.
Thank you for your feedback, I have little knowledge of the German language, and at the moment I have to use the dictionary a lot, and I read many articles from online newspapers and magazines.
