I think Oscars cats werent allowed in the city because they were actually tigers and exotic cats not domesticated ones found around Rapture.

Also dead puppies can be found in some places (I believe there is one in Porters office in Minerva's Den) and one can be heard being killed by a young jack in one of suchings audio diaries.
