When the correspondence pills up in front of the house of the eighty-year-old Ruth Elliott, the mailman looks through the window and calls the police since the lady is dead. Grissom, Catherine, Warrick and Ray O'Ryley come to investigate the case and they find Ms. Elliott being eaten by their several cats. But Grissom finds that she was stabbed on the chest. Two girls have witnessed a discussion between the next door neighbor Debbie Stein and Ms. Elliot. Debbie, together with Ms. Elliott's son Tyler, become suspects of the murder. Meanwhile, Sara, Nick and Captain Brass investigate the case of a BMW blown up with a bomb. They interview the driver Marcie Tobin and the mechanic Marcus Remmick that tell that Marcie overheard a noise in the engine. When she popped the hood for Marcus to check, he saw a bomb and they ran to seek out protection and the car exploded. They learn that the only person that has access to the car is her husband Johnny, who is the foreman in her father's company of construction and demolition. They interview her father Barclay Tobin and Johnny and start to investigate the available evidence.
"Cats in the Cradle..." is a great episode of "CSI", with two good storylines. The first one, with the gruesome death of an old lady and a surprising conclusion with the identity of the killer. The second episode, with the investigation of a blown-up car and Nick and Sara learning the truth. My vote is eight.
Title (Brazil): "Gatos na Cama" ("Cats on the Bed")
