Missing pets on Steam?

I've tried this game on Steam and noticed that some pets are not there. It's not possible to buy the squirrels and there's no eagle.

Are they going to be included in that version too some day or not?

Hi Juniper! We're happy that you're checking out the newly-released Steam version. The Flying Squirrels and Eagle will be available in a future release of the Steam version. Make sure that you update your game when you see that a new update is available!

Nice. I really like the squirrels.

What about the Big Fish version?
