My beloved cat Rascal (3 years) died last Sunday from a bladder infection. I have another cat Peanut who is also 3. Peanut has started to act a little squirrely. He is eating and using the litter box, but he likes to hang out in my room quite a bit which he has never really done before. My bed is where Rascal loved to sleep. I am convinced that Peanut is grievieng for his brother. I have let Peanut smell Rascal's collar hoping that the familiar scent might cheer him up. These are my first cats so I am somewhat uncertain as how to help Peanut. Any suggestions?
