"We just took the little ones out, they were really tiny and fairly new, and the house was really smoky," Lieutenant Jim Lamb told the Naples Daily News.
"The owners were very happy" that the firefighters were taking the time to help out the little kittens, Bonita Springs Fire District's Natalie Hughes told The Dodo.
The mama cat, who wasn't injured by the smoke, stayed behind. "She was quite fine staying in the house," Hughes told The Dodo. "She wasn't too pleased with everything that was going on."
Like many fire departments across the country, Bonita Springs has invested in little oxygen masks for animals - an adorable and lifesaving tool that can make a world of difference in saving pets during emergencies.
