I'm still seeing red

Okay so last night has me still seeing red and I'm still extremely upset. Last night everything was calm. My boyfriend was watching YouTube and I was doing my diamond painting. our 1 year old cat was bouncing around the room playing when she was overzealous and her claw caught the curtains. My boyfriend literally lost his damn mind and proceeded to get up and chase her out of the room and threw a shoe at her. I went off on him immediately oh, I told him that his behavior was completely unacceptable in that she is pretty much still a baby, she barely stopped being a kitten.

He started to make a big deal about the curtains and it really upset me and I told him that her life is irreplaceable they wants her life is gone her life is gone but curtains something that can be replaced. He tried to justify his actions with the fact that animals are killed so that we can eat meat. so I told him yeah but we don't have any intention of killing our cat to eat her so that has nothing to do with the life of our cat versus you throwing a shoe at her but you're mad that she was playing and accidentally tugged on the curtains.

I literally don't know how to handle this situation. We've had so many highs and lows and so many struggles in this relationship that it's not even funny and I'm just getting really tired of everything. And he doesn't seem to get or understand why his behavior is wrong and why it's not okay to attack a creature that is literally so much smaller than him. She's not even 8 lb. At the speed and velocity that she was traveling he could have done some serious damage to her if not kill her hey. I'm having a hard time moving past this because I don't condone animal abuse.

She used to love the hell out of him and now she's terrified of him. I mean she literally cowers away from him. He is coming in the room quite a few times and now she's hiding under the bed when he enters the room.
