FARMINGTON HILLS, MI - Someone believes they may have spotted one of Michigan's missing world record cats feared killed in a house fire.

Arcturus and Cygnus were inside the home on the 34000 block of Quaker Valley Lane when fire quickly destroyed it on Sunday, November 12, 2017. Owners Will and Lauren Powers made it out safely, but believe the cats did not survive.

Now there is new hope after someone said they saw a "beast" of a cat near 11 mile and Farmington Road on Monday night. That "beast" may have been Arcturus, the world's tallest cat at 20.1 inches. He sort of looks like a leopard.

With this new hope, Powers is offering a $25,000 reward to be paid in Bitcoin for the safe capture of Arcturus. The reward also applies to Cygnus, who has the longest tail of any cat who ever lived, or either of the two other cats inside the home, the Powers' third cat, Sirius and a neighbor's cat, Yuki. "I've been saving my bitcoin for years," said Powers. "Now is the time to use it."

If you spot Arcturus, call Oakland Co. animal control (248-858-1090). Powers says don't be afraid of him and don't chase him. "He looks scary, but is a sweetheart," said Powers. You can also download the free Tile Tracker mobile app. If you come within about 300 feet of Arcturus, Powers will get an alert if the collar is still him.

Family, friends, neighbors and even strangers have been conducting searches for the cats near the home which was in a wooded area off of Farmington Road near 11 mile. There are also traps set out.

Powers says if you want to help, you can make a donation to the Ferndale Cat Shelter where Arcturus was an ambassador by clicking here. You can also make a donation to the shelter at: 821 Livernois, Ferndale MI 48220.

Will and Lauren Powers say they lost everything in the fire, but the only thing that matters to them are the cats. "If the death of our cats isn't meaningless and can help another family love their cats like we loved ours, then this tragedy can have something good come from it."
