Hi, We just got a 2 month old toy fox terrier. She is coming into a home with 2 resident cats, who are 5 and 6 years old. We have been able to have interactions between one of the cats and the puppy, but the other cat has retreated into her "safe haven" and won't come out, even though the puppy has not attempted to approach her. With the other cat, we have been conducting supervised interactions which have progressed to the point that the cat will not hiss or react to the puppy if the puppy calmly approaches her. Sometimes, she simply turns and walks away. However, there have been a couple of times where it is clear to us that the puppy wants to play with the cat, and in those instances, the cat has hissed and taken an aggressive stance. Our ultimate goal is to have the cats and puppy coexist peacefully without human supervision. What do you recommend? Do you have any other tips which would be helpful in this transition? Thanks!
