Is there any opinion that holds one may play or touch a pet on Shabbos (even though animals are normally muktzeh on Shabbos.) Specifically one that is meant for this purpose (to play with.) I heard recently that the Maharach Or Zaruah mentions such a thing. Is there any such opinion found?
It seems From the Igros Moshe OC 5:22:21 that pets are different and are not like other animals which are muktzah see the tshuvah inside it is very short.
