I don`t know anything about it because the bible don`t say but it would not surprise if the animals has a lot better chance that their owners.
See #21.
Animals did not and cannot sin, therefore have no need of salvation.
They are part of the fallen creation, now, because of human sin.
They are not under the same curse/judgement that we are so why would God condemn them to eternal nothingness when they have done nothing wrong?
Romans 8:22
