@JezC We have had to go to extreme lengths with Oliver.
Where he was before we got him, he was allowed to roam free, but because of neighbours/dogs etc where we are, he stays in and gets escorted round the garden as much as possible.
Of course when we first got him, you're supposed to keep them in anyway, but he went bonkers, at all times of the day or night, I can only guess it wasn't dissimilar to having a baby around.
Now we drug him up with Beophar, and he's much more mellow and most of the time doesn't go crazy at all hours.
