For cables, etc I was recommended Grannicks bitter spray - used it when they came to me and have relatively few problems now. These days they just like knocking cables and pens off my desk ( but only when I am there to see it
)
As for being wild, we've always had adult rescue cats who have been shown plenty of love and have shown love in return over time, albeit, sometimes with limits on patience/ ease of picking up/handling. In contrast to our previous cats, my 2 bengals are incredibly easy to handle and very tolerant. They are not in any way wild or aggressive in behaviour.
Neoow is right in that they can be obsessive little.... munchkins. Babbage knocked over the bin in the bathroom 3 times this morning as I was getting ready for work seemingly just because he could - he played a bit with some of the fluff from the drier which was in the bin. Saturday evening he knocked a glass of red wine all over the sofa, table and my new cream-coloured rug. My attempts to clean it up were, apparently, a game designed just for him. I ended up mopping wine out of the rug with one hand and holding him back with the other.
