Hello,
 
I'm so glad to hear that someone else out there is concerned about the animals.  I've prayed every night since 1994 that the Lord will take my dogs when he takes me in the Rapture.  I've actually agonized over the idea of their being left behind.  As I've prayed about my dogs, God has led me to scriptures which seem to confirm that he will Rapture our beloved pets along with us.
 
Noah took animals on board the Ark and the Ark is a symbol of our safety in Christ Jesus.  I realize God intended to repopulate the earth with these animals, but there are dozens of ways he could have accomplished this.  After all, he is God!  Later, I was led to read Exodus and how the children of Israel were miraculously taken out of Egyptian bondage - another archtype of the Rapture.  In Exodus 12:32,  the pharoah instructs them to "also take your flocks and your herds, as ye have said, and be gone: and bless me also".  Then, in Exodus 12:38, it states, "and a mixed multitude went up also with them; and flocks, and herds, even very much cattle". God didn't have to put this in his Word.  I think he purposely mentioned the animals because he foreknew we would be worried about them.
 
Acts 11:14 says that all our house shall be saved.   But the best scripture, by far, to put our hearts at ease about our pets' welfare is Romans 8:21 which states, "Because the creature (animal) itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God."  It doesn't get much clearer than that.  I believe that God knows how helpless our pets are and that they would be left at the mercy of wicked humans after our departure.  He knows our hearts and how we long for our furry family members to be saved along with us.  Call it wishful thinking, but I believe our pets are going up hither right by our sides.  Hope this helps.
