I might be getting a chihuahua puppy ive wanted 1 forever but i was wondering if i could introduce it to my 2 older female cats? they r both really friendly one of them even comes and puts her head on your shoulder and her arms around your neck if your lying on the bed. but she also catches mices n birds and once attacked a labrador and scratched its face.. my other cat is a hopeless hunter. ive heard you can introduce chihuahua puppies to cats succesfully but im not so sure.
