I have a chihuaha named Roscoe, who has been raised with my cats, and thinks he is a cat, he is terrified of dogs!!! I have two cats, a male Siamese named Choco that weighs about 25 lbs, and a female, unknown breed, gorgeous with long gray hair and was born w/o a tail. We just got two kittens, Tucker and Muffie, they are 3 months old, both orange and white and hilarious. Roscoe plays with them just like another kitten would!!
