This is true because God does nothing against love. But technically we can see it from the demon possession of the 2000 pigs in Mark5.
11 Now a great herd of swine was there at the mountain feeding.
12 So they entreated him, saying: Send us into the swine, that we may enter into them.
13 And he permitted them. With that the unclean spirits came out and entered into the swine; and the herd rushed over the precipice into the sea, about 2,000 of them, and they were drowning in the sea (Mark 5).
We know from I14 and from U255, that the method of demon possession of a human is that the demon attaches the heavenly modem link of the human interface to his angelic soul or to his share of an angelic soul. He needs to do this because at night when we sleep our spirit goes out and runs on the heavenly angelic server until we wake up. During this time we believe that we upload the cache of our daily memories into our heavenly angelic server. IF we are born again then we have a dedicated angelic server in the form of an angelic body. If we are not then we share an angelic server which is an angelic soul.
Mark 5 shows that demons managed to connect their angelic servers to the heavenly modem link from a pig. They did this with the permission of Jesus. This means that pigs have heavenly modem links which means that they too have heavenly animal servers. Angels have pets too!
In fact any animal which sleeps and dreams most probably has a heavenly animal shared server, to which it uploads its memories for that day during the night.
So God actually has the characters of all the pets that have ever existed in his heavenly animal servers. It is not as if God does not have enough storage capacity up there!
Therefore in the kingdom of God, we shall be able to choose which pets to
resurrect from this server.
