Marty and his 15,000 Instagram followers are forever debunking the myth that rats can’t make good pets. Marty is a dumbo rat specifically, which are rumored to be the sweetest and most gentle. In May of 2013, he was brought home from PetSmart and his owner could tell he would be a photogenic pet. She soon started posting Marty, his friends, and all their little adventures to social media: Marty reading a book, using a calculator, wielding a lightsaber, and eating all the snacks he can get his tiny hands on. BuzzFeed reported in September 2014 that he will “Change How You Feel About Pet Rats.” Sadly, the little guy died recently but his spirit lives on at instagram.com/therealmartymouse.
