I would like some advice on the plug in gadgets that release cat phenorones. Do these items really work? I have major cat trouble at the moment. Phoebe my elderly cat has scratched my arm rather badly but only because she wanted to escape from Bertie. He is fascinated by Phoebe and they eat and drink out of each others bowls! I went to sit in the conservatory and Phoebe who could see me through the glass roof cried loudly to be let in through the bathroom window.There is always lots of growling and hissing from Phoebe but Bertie does no hiss or growl only chases Phoebe around. I am off to Italy on Saturday so the cats will be left to their own devices. Any suggestions? EJ
