"The neighbors said they were imagining it because they didn't hear anything," the BEAR League wrote in a Facebook post.
The homeowner discovered the sound was not her imagination when spring arrived and she heard the unmistakable sounds of a mother bear waking up under the house.
"We arrived immediately. We un-invited Mama Bear, not yet aware there were four more bears under the house," the BEAR League said.
The group said the mother bear had given birth to three cubs last year and ended up adopting a fourth cub that had been orphaned.
"It was quite the scene to then watch the four yearling cubs emerge from the opening and join together on the other side of the fence to venture forth into 2022," the BEAR League wrote.
