That's it - first thing on Monday I will be phoning the vet to book an appointment to get Dijon's bits checked out. 4 months since castration, and he is spending more time that ever trying to mount Mabel, is 'hmm-hmm'ing so loudly we can hear it from the next room, and this evening he sprayed full force when out in the dining room, sending wee all over the carpet, piano stool, piano (as high as the keys) and cupboard next to it. Fortunately he just missed me.

Unfortunately I had spent most of yesterday morning cleaning his spray stains off the carpet with the Vax. I suppose I'd provided a blank canvas.

As I type, he is back in his cage with Mabel, and is going in circles trying to mount her, even though they've been out and running around for most of the day. We have noticed that he tends to pester her when we approach - if he's excited to see us then he redirects his excitement onto Mabel.

However, she may be getting her own back... we've noticed that several of his whiskers on one side appear to have been chopped off - badly, they even have split ends. Could it be Mabel?...
