Everything you said is Sid to the T!! He is into everything!! He loves playing in my mesh laundry hamper. Plays fetch, and jumps around like a rabbit! One thing he has done a couple of times is something i have never seen. When he is sleeping he talks, alot!! Its amusing, but is that normal? I know the siamese is known for their voice. As for siblings, i think all the kittens fused together to create one big monster, my Sid!!!
