I may have lost my best friend.

I got extremely pissed off with my cat and subsequently ended up chasing him a round the flat and threw him out of the window (ground floor so not a huge drop). This is due to the fact he peed on my bed. I had to go out to get a new duvet because it’s basically now ruined. I decided to get new pillows while I was there too because they’ve just about gone flat. I don’t normally get angry with him but I’m genuinely not in a good mood after being kept awake by things that others are refusing to change. I am so tired and fed up. I now may have made my best friend run away because I got angry and launched him out the window. I’m hoping he comes back but he hasn’t yet.
