I have a DSH tabby, Miss Mikura.

She wasn't exactly a rescue but her former owner kept her in a cat carrier her whole (1 yro) life. She was terrified when I got her, I love her so much. she has some strange habbits(?).
she hates other humans. Tolerates my husband, barely tolerates my son, but any and all other humans that have come into my house over the past 2 yrs get attacked if they are in her way to go hide under the bed.
Yes, she has hurt the occasional idiot that says "naaah, animals love me!" like my dad... and others.
She likes to chew on cardboard.
She will follow me all over the house if I am busy doing stuff.
If I am taking a bath, she sits on the side, plays with bubbles, may take a nap there if i fold a towel for her to sit on. If I take a shower, she sits on the side and looks preturbed. Either way, when I get out, she frantically meows at me!
What is your guys take on Mikura's general behaviour?
