Free House Mouse eCards - These are so darn cute, even though they are mice, not rats. I spent a small fortune buying their paper cards, mouse pads, stamps, magnets. But their eCards are free!
Here are a few rat themed PAPER greeting cards I found at Amazon:
Pack of 12, Rat Chinese Zodiac Symbol
Rats Rule Greeting Cards, Set of 6
Cute Grey Rat Greeting Cards, 6 x 6 inches, set of 12
