    Hi Jonathan

    Before you proceed with an in-home consultation, I wanted to mention a few things:

    1. It is not advisable to pet any cat, such as Sylvie, that exhibits negative behaviors like hissing or growling. Doing so may reinforce these behaviors, rewarding them for their aggression.

    2. Consider placing a webcam or recording videos of the cats’ interactions. This can be helpful for both you and a cat behaviorist, as it allows you both to review the cats’ body language and identify any signs of passive aggression.

    3. You may find these articles beneficial for understanding cats and the subtle conflicts that can arise between them. https://cats.com/how-to-tell-which-cat-is-dominant and https://cats.com/reduce-conflict-between-cats

    Wishing you all the best with the kitties—they are very lucky to have you!
