Thanks Icould only see first few lines of that text.
Very difficult as he is in Spain cos have no idea how vets work over there,
I still think first port of call is vets to rule out any medical probs but think this is a cat that has been terrified in some way by people.......owner maybe?
Could be an ex feral? off the streets and its history would be useful to anyone trying to treat.
Zykline (sp?) may help but in this country a referral to a behaviourist like Vicky Halls would be the probable way forward. She may do an over the phone thing cos she has been in Europe recently doing talks etc. Her website can be found on a search.
Another way forward is to get a toy on string on a stick and use that to try and distract away from feet or when it attacks in other situations. It may or not help.
