This Week In Adoptable Animals: A Rabbit And Guinea Pig In Love And Dogs And Cats Galore (PHOTOS)

WASHINGTON -- Have you ever seen a rabbit and a guinea pig in love?

This week's adoptable animals are almost too adorable to bear. They include a 3-month-old puppy, a sweet orange kitty, a rabbit and a guinea pig who are BFFs and a friendly baby rat named Marshmallow.

There's also more cute dogs and cats of all ages and breeds than you can toss a ball for. And did we mention the bunnies?

The gorgeous babies below -- 19 in all this week -- come from the Washington Animal Rescue League, the Washington Humane Society and the Animal Welfare League of Alexandria.
