Our Chihuahua mix Maggie loves our cat and to our surprise, Birdie the cat loves Maggie. They are so much fun to watch... Birdie still has all of her claws so she could really hurt Maggie if she wanted to but she is the friendliest cat we have ever had and she has never even hissed. Usually the playing starts when one of them jumps on the other one. Birdie is about 9 years or older and Maggie just turned 1 before Christmas. Best of friends!
