Frankie the cat was rescued recently after surviving on nothing but McDonald's food for a year. As an abandoned kitty he would follow cars in a drive thru and accept pieces of food people threw out for him. It's not the healthiest cat food out there, but hey, it beats digging through people's trash.
When he was rescued he would not eat normal cat food, instead looking at it like "What is that?". But, you'll be glad to know he's kicked his fast food addiction, got the full veterinary works and is ready to be adopted by a loving family.
