I meant to add this earlier. My brother's cat Louie is bonded to him. He was 2 weeks when found and hand fed by he and mom for a week or more before he began drinking out of a bottle cap. Anyway, he was hand-raised my Mom and Bro and so has a big attachment to Bro. Louie has one of Mom's blankets that he slept on, his woobie, and Joe has never washed it since Mom's passing. Louie loves his woobie.

I have no clue of the derivation of "woobie".
