thanks so much for all your support. After a 1 hour lecture by the specialist (complete with showing me diagrams) I felt completely brain bashed! She was doing various tests on Katie at the same time, but wouldnt even let me go out to the carpark for a few minutes with her while waiting for some drops to take effect! Anyway, there are risks in not doing it and even more risks in doing it, especially for JRs apparently. So, if I have my way in all this, it wil not be done. As some of you say, animals find their way around very well and at great speed on occasion.
