Next tonight we have a sign of hope out of those floods in colorado. A lot of lives were saved, because of a lesson learned from hurricane katrina. If you want to rescue people, also rescue their friends, with four legs or feathers or even fins. Here is abc's meteorologist ginger zee. Reporter: No pets left behind. That is the strategy, as thousands of people were rescued in colorado, their pets were rescued, too. Mostly dogs as you can see. But some cats in crates and other animals I couldn't tell what they were inside crates. I think at least a bird, I saw a bird cage. Reporter: Today we learn almost 900 pets have been air lifted to safety. All part of a mission to convince their owners to evacuate. We've seen more and more dramatic pet rescues in the years since hurricane katrina, when people died, because they didn't want to leave their pets behind. They are members of our family. We are neighbors helping neighbors, that includes the entire family. Reporter: In colorado we saw heart wrenching images, the horse waiting out the floods all alone. Today, word is, socks survived. We also witnessed the real life cowboys saving those who couldn't save themselves. I helped the family out that looked like they would have to leave their animals behind. Reporter: And proof that our pets are our everything. This is where I slept since friday. Reporter: Bill pots slept in his car for five days until he could get his cat baby boy. I have to take care of him. If you had kids, you'd know. Reporter: I was there when the thomas family evacuated their home. They weren't going without their three dogs. Hary, happy and digger. They are coming. Reporter: The national guard's most recent tweet says it best. Pets are people, too. Ginger zee, abc news.
