:) 2014-02-19 04:15 research regarding which cats are allergene donors and which are not is ongoing 2014-02-19 04:18 so far the only result seems to be: the allergene is NOT the hair (usual misconception), rather the proteines from either the saliva (fur cleaning) or the skin flakes 2014-02-19 04:19 but maybe neither, but rather some secondary effect, like with "hausstaub milbe" (sorry dig fails on that) 2014-02-19 04:21 House dust mite. google shows a nice picture. 2014-02-19 04:21 well, so does wikipedia 2014-02-19 04:21 the allergenes from that are the proteines in their shit 2014-02-19 04:21 viric has quit [Ping timeout: 240 seconds] 2014-02-19 04:22 the wikipedia article sounds rather enthusiastic: http://en.wikipedia.org/wiki/House_dust_mite 2014-02-19 04:22 "cosmopolitan guest", "flourish", "potent" 2014-02-19 04:27 viric has joined #qi-hardware 2014-02-19 04:38 biologists are kinda mad like this 2014-02-19 04:40 btw maidan square battles 2014-02-19 04:45 http://www.bbc.co.uk/news/world-europe-26249330 2014-02-19 04:53 viric has quit [Ping timeout: 240 seconds] 2014-02-19 04:54 michael_lee has joined #qi-hardware 2014-02-19 04:55 viric has joined #qi-hardware 2014-02-19 05:41 arielenter has quit [Read error: Connection reset by peer] 2014-02-19 05:41 arielenter has joined #qi-hardware 2014-02-19 06:11 wej has quit [Ping timeout: 252 seconds] 2014-02-19 06:55 arielenter has quit [Quit: Leaving.] 2014-02-19 07:09 wej has joined #qi-hardware 2014-02-19 07:17 for the german speakers: TV invented a new word "Litionenbatterie".
