Unfriendly guest

Got up this morning to find my neighbours cat in my kitchen. He's not the most friendly of cats and was hissing at my two, who were keeping their distance. I was wfh and throughout the morning kept checking - hours later he was still there and getting more and more agitated. If I even tried to set foot in my kitchen he started snarling and spitting at me. I ended up messaging my neighbour who came home from work to try to get him out. Even she wouldn't go to close to him though as he was so worked up by now his reaction to her was no better! Fortunately he was eventually coaxed out when we opened the patio doors.
