Everything you just said accept the word cat is replaced with AK-47:
Okay, so basically a pet owner with their AK-47 throws up and they die. The AK-47 is scared and when the owner dies it falls into despair. Then the AK-47 finds another AK-47 and decides to go with it, but the dog appears and the other AK-47 is attracted to it. The dog is really smelly. The AK-47 falls into despair once more, and then finds a burger. Someone says the burger is bad and will kill the AK-47, and then the AK-47 falls into despair once again, and then dies.
