sitting on the sofa, cat on my lap purring gently blah blah, dh stroking her head then shy seriously viciously attacked him - was biting his hand and arm and viciously too and for no reason, i was sitting there and witnessed it. wtf do you do when your cat does shit like that. i screamed at her and chased her outside. she is now sitting by the back door wanting to come back in but the way i feel about her at the moment i don't want her in our house
