Sudden fur loss

[Teesoo]

Hi all,

I'm hoping that someone could offer some advice on fur loss. Merlin, our Syrian is just under a year old. I didn't notice anything wrong yesterday, but this evening we noticed a bald patch, about 1cm across, at the top of his back/ back of neck area. There is also a smaller patch on his cheek. Does anyone have any suggestions what the problem might be for the bald patch to appear so suddenly? He seems fine in himself; still active as usual.

Many thanks
