We have 2 year old seal point siamese cat. He doesn't ever go after my spouse or myself. He often will "attack" our 14 and 9 year old sons, unprovoked. Usually he hides and attacks their legs as they are walking around the house, often drawing blood and leaving a scratch. Never done it to an adult. We've tried giving him more attention, less attention, more playing, no playing, cat nip, calming treats, changed diet. He occasionally scratches the furniture but will run away if you clap your hands at him. It's sort of funny, if you do yell at him for misbehaving he runs to his scratching post and takes his anger out on it like an angry teenager. We have a little baby coming in a month and feel we are out of options. We do not want to de-claw him, after reading online and the abundant negative and cruelty issues that come with it.

Are last two options seem to be de-clawing or finding him a new home (no one will love him like we do.)
