Refurb the cat is missing a hind leg--one that a cat might normally use to scratch her neck. That doesn't stop her from trying, though! Her phantom limb does the job.
When she's not scratching or playing with her human or canine friends, Refurb (that's short for "Refurbished") raises money for animal shelters. That project began last year when a Something Awful forum member paid a $10 donation to an animal shelter in exchange for a paw print autograph. Other people in that forum and on reddit wanted paw prints, too. Together, they raised about $1,000 for animal shelters.
