We call unknown mixed breed dogs mutts or Heinz 57's. I'm not sure what we call cats that are mixed. I like moggy better. She looks like a miniature white tiger with those stripes on her face. I just love those ragdoll cats. If I didn't take in so many strays, I'd love to get my hands on one of them. I can't ever buy a cat cuz the homeless ones always find me. LOL. Love her coloring!!!
