Do you think than Cats and Dogs will be the only pack to include pets?

There was a survey with a pack with smaller pets like birds and reptiles, and they would be breedable. I really want that as I love birds and reptiles in my sims games, and they were missing from cats & dogs. I think at some point they will do a farm life game pack or expansion, as this is so requested by the community, so then maybe they'll introduce horses, but who knows really...
