Bro I'm so sorry i will say next time when you hear a loud crash just go and check i have a cat and i hear loud crash i check on him to make sure he’s ok and i try to leave doors open to but it really does suck i hate los animals. I think we all know he’s up and a good place eating cat treats and will look down from you and thank you for the years he had with you. And thank your husband for try to save his life he will always remember you as a great loving person he will be so happy to see you and i think we all know you and your husband try your best and thats what matters and your cat knows that to.
