It’s getting “beary” contentious.

A man who has been living with a 550-pound black bear under his home for the past month has officially reached his breaking point — threatening to sue the California Department of Fish and Wildlife after he says it left him to deal with the massive creature on his own.

That’s a claim that the department is calling a bear-faced lie, The Post has learned.

Ken Johnson, of Altadena, Calif., has been tormented by the uninvited furry guest who has occupied the small crawlspace under the house since November 30, causing severe damage to his home and many sleepless nights. 

Infuriated, Johnson is threatening the CDFW with a lawsuit after he claims the department has stopped efforts to remove the bear, according to KTLA.

“This has gone on long enough, and it’s something that they should deal with. It’s a tagged bear. They’ve dealt with it before. They chose not to euthanize it, and now it’s back and it’s just going to keep on doing this,” Johnson told KTLA.

The CDFW is telling a beary different story.

“Despite very limited staff, CDFW biologists have been in constant communication with this homeowner since this bear was reported entering his unsecured crawlspace in November. We remain committed to helping this homeowner and have never indicated otherwise,” a CDFW spokesperson told The Post. 

“I’d really like to comment, but I’m not going to until I have proper legal representation,” Johnson responded to The Post.

Resources were on scene shortly after the bear first arrived at Johnson’s property, deploying a cherry and caramel scent spray designed to lure the beast out — with no luck.

A massive metal trap filled with fried chicken, sardines, shrimp, peanut butter, and fruit was brought in … but it caught a different bear that was also making its rounds through the neighborhood.

The bear finally emerged from under the home on Christmas, in footage obtained by The Post. The bruin could be seen making a quick loop around the property early in the morning before retreating into the crawlspace.

It was shortly after the bear’s appearance when Johnson was allegedly told the department was giving up on removal efforts.

“I felt very defeated. I just dropped. Now what? It’s all up to me, and I’m supposed to watch my phone when he comes out in the middle of the night? Or sleep in the kitchen and listen for him every night?” Johnson told KTLA.

The bear continues to wake Johnson up at 5 in the morning. “I wake up, toss and turn and then I think I hear something, is he under my bed? Last night I didn’t get much sleep,” he told The Post.

Johnson’s home has been taking a beating from the bruin — he had to turn off his gas on Christmas Eve after spotting damage caused by the creature.

“I can’t take a hot shower. I’ve got to monitor the situation all the time,” Johnson said.

“The California Department of Fish and Wildlife is committed to helping Californians across the state who are having unwelcome encounters with wildlife, which can cause stress and pose complicated challenges for peaceful coexistence.” the department stressed to The Post.
