Everyone in this world is either a Cat or Dog (Warning Murder, Life threats and a VERY scaring music video made by @Draikinator but an interesting music song

You live across from your neighbors house her name was Kat and and another cat man named Bruno you sometimes talk to them, You play instruments in your room a lot of the time, Kat was "friends" with Bruno but to you it was lovely between them and you like seeing them together, one day Kat slept with a Wolf named Armadillo and he was the next NEXT door neighbor of Kat the house after Bruno, then another day you were in your room playing your violin then you look out your window and see Armadillo outside Kats door with a sharp piece of glass hiding behind his bouquet and when Kat opens the door he pushes her and take out the sharp piece of glass and suddenly Bruno comes from behind Armadillo and hits him in the back of the head with the sharp side of a shovel killing him, Armadillo falls to the ground dead and Kat looks at Bruno with fear, disbelief and Thankful while tearing up and Kat hugs Bruno and suddenly they turn around to see you watched the whole thing

What do you do?
