Welcome to Pet Talk! I think what we see as our cats' quirks are probably just normal feline behavior. My Mitzi also "digs to China" when using the litterbox; Mishi doesn't like to get his velvet paws dirty so he paws outside the litterbox thinking it's going to do the job he's my strange big boy. We know he's a bit "tetched" as he suffered a severe head blow before he was rescued; it makes him a bit goofy, but very special to me.

They both LOVE plastic bags and I know it's not good for them, but it is funny to see them chomping on the plastic.
