We have two cats and two Basenji?s, but the basenji?s grew up with the oldest cat.
They live togehter as a family, but the first meeting between Buana (oldest Basenji) and Spaik (oldest cat) was heavy
Spaik was so mad at us he went under the bed and didn't show himselfe, when Buana got to close he hit Buana.
Cats usually need time to get used to them, for you I think you need to watch them the first weeks constantly.
From their behavior you can see how it's goint between them
