Be patient, it took almost 6 months for me to transition our new kitty into the mix. I have 3 dogs all of them grew up with cats when they were babies. For some reason my now 8yr old female would not accept the new kitten. It was pretty bad at first, I was worried she might hurt him. I kept the kitten in the big dog crate when the dogs were inside, taught the kitten to stay on higher ground.
Now if the dogs were outside, I can let them in and she will walk right past him and pay him no mind. They can even lay in very close proximity of each other. Of course I wouldn't trust the dogs alone with the kitty. I tell him "never trust those dogs".
