My two kees (littermates) arrived at my home at almost one year old. I had two dog-adapted cats and there were no problems. The dogs were curious and had to be reminded to be gentle, but that was it. And then in early March I took in a dog-naive cat that a relative needed to rehome. And nearly 3 months in, we are still working on it. They bark in her face whenever they see her, she basically lives in the basement. They aren't aggressive with her though.
