Sounds like Vibrations and sounds were been present in the building leading up to the collapse.
Animals may have been aware of it.
But not necessarily any survival instinct.
I had a friend who barely escaped a burning “apartment” upstairs in an old 2 story home (downstairs was a store that had caught fire). He was leaving on the outdoor metal staircase with his cat and the cat freaked out from the fire (not on the stairs) and the smoke and went back into the house.
A good friend of mine had her home burn to the ground a couple months back. Same thing. Had 4 dogs, and two got to the front door with her and ran back upstairs to the “safety” of the bedroom. The did not survive.
