Okay so I followed the instructions but I was unable to breed the animals or keep them in the cages I had built, using those specs, all of my animals got loose and disappeared, as In they ran away and I have no idea where the went, and I looked all over creation for them. I was never able to breed the animals, and I believe this is an aspect of the game that they still have not incorporated into the game, and if they did its buggy as hell.
I have the cages still up in case the next update (when ever that will be) and they introduce breeding the animals into the game or fix the severe bugs in it.
