There's no news of this incident in English on Google News. (Searched using firefighter cat Denmark)
Kitty Saved from Fire, Happy Reunion cites a reddit commenter mentioning an article from JV.dk. Unfortunately, I can't read Danish, but the sentence mentioning cats is
På grund af den kraftige røgudvikling måtte flere katte hjælpes ud af brandmændene.
Did a firefighter rescue cats from a house while it was still burning? Or was it more a case of helping them out after the fire had been extinguished?
