Is there anything i can do to prevent an outdoor cat from my window that is eye level? My Cat is an indoor cat and the two are fighting through my screen.
If the only place the cats can contact each other is the window, I would try spraying or placing something on the window that has a strong scent. This could include a nice big spray of air freshener, some vinegar, a cut lemon/lemon juice, or something similar.
This should hopefully deter them from getting near the window before a fight can take place, and eventually they should learn not to go to the window.
