article: When Jason Archinaco's wife said she wanted to get a fourth cat, it is unlikely that this is quite the  addition to the household she imagined. Because, since Monday, the family have been sharing their home with arguably Los Angeles' most famous mountain lion, P-22. The cougar, the other name for the species, has made his home in the crawlspace under the house in the hilly Los Feliz neighborhood - and has so far resisted all attempts to get him to move out. Scroll down for video . New home: The lion - known as P-22 - was found by workers in the crawl space at midday on Monday . Rescue: Attempts to get the lion to move out - including firing tennis balls - have so far been unsuccessful . Resident: The beautiful animal may have been living in the crawlspace for some time before being discovered . Workers discovered the big cat on Monday at noon, as they were trying to install a security system. Ten hours later - despite animal welfare officers using a prod, and even firing tennis balls and bean bags at it - he was still refusing to move. 'I don't think he's going to come out,' Archinaco told  KNBC-TV. 'He's probably been living here for a while. 'He thinks this is his den.' But then, this level of determination will probably come as no surprise to those who know the tale of P-22. It is thought the lion crossed the 405 and 101 freeways more than three years ago, as he travelled from his home in the Santa Monica Mountains. He has been living in nearby Griffith Park ever since - where scientists managed to catch and tag him. But his fame reached new heights after National Geographic photographer Steve Winter managed to capture him walking in front of the Hollywood sign in 2013. Then, last year, the big cat survived mange and a meal of rat poison to become apparently healthy again. Fame: P-22 is best-known for being pictured in front of the Hollywood sign in 2013 . Hiding: It is thought the lion crossed two freeways to get to his home in Griffith Park, but it is not known how long he has been living in the crawl space in the Los Feliz hills . Beanbags: The animal rescue workers have even resorted to using beanbags to move the lion . However, all this is nothing to the furore surrounding his latest move. The LA Times reports a scene worthy of any film star - with news vans filling the street, helicopters flying overhead and even a live news feed on a local channel reporting the latest. However, they were not rewarded for their patience, and state wildlife officials cleared most media and gawkers away from the area as night fell. They continued with their attempts to dislodge P-22, starting with poking him gently with a long prod, but that did little — other than temporarily lose the pricey GoPro camera they'd attached to the end of it that fell off. They then attempted to fire a tennis ball cannon into the crawl space with hopes that at least the noise and commotion would scare him out, a tactic that often works with coyotes. Next, they fired small bean bags, the same kind police sometimes use for human crowd control, toward the cat. Live feed: The incident has created quite a furore - with people watching it unfold live on television (pictured) All of the tactics, shown live on streaming video, drew mild reactions from P-22, but none came close to drawing him out or even getting him to significantly move. Wildlife officials said late Monday night that their next move would be to just wait. 'We're going to let him settle, we're going to let everything calm down, we're going to be really still and give him time to get out of there,' said Janice Mackey of the California Department of Fish and Wildlife. Archinaco said he and his wife have three ordinary house cats and had thought about adding to their numbers. 'My wife wanted a fourth one,' he said, 'but not this way.'
