on thursday my mother and I went to the fish market, bought a bunch of fish... anyway as usual we gave our cats some of a blue eyed cod fillet and they didn't realy seem intrested. last night I got up to use the toilet and noticed the stuff glows in the dark, literaly: the room was pitch black and all I could see was this piece of fish. now i'v never heard of this and I don't actualy eat fish myself but I can't see it being normal? is this stuff toxic or something? it wasn't exactly cheap!
