my sister came home at 6:30pm and her cat was lying on the floor in the middle of the living room dead
she rents a house that has a basement apartment and the guy who lives down stairs came home at around 5:30pm and he saw her in the kitchen window sill, where she always goes when some one is on the side of the house

my mom thinks that maybe the cat climed the entertainment center and jumped off and hit her head and had a brain hemerage or something like that

the cat was only about 1½ years old
i don't know anything about cats but the whole thing is very strange
