The software needed to run them includes Steven to run wolverines etc, and the It monster to run the pets and both are too annoying to make it worth while.
They are not pleasant like a barking dog all the time or a vicious predator in your back yard,
So henceforth it all stays in Time Stretch Earth and has no place in our peaceful heaven escape from all of that.
We add a planet to the stretch and use it just for that.
To see animals and pet them and have pets or whatever.
