Caterpillar

I suspect this is a moth caterpillar. I thought I had seen this one in my research before, but came up blank. I have photographed this caterpillar before, but not posted it. If anyone wants to have a go at an ID, please be my guest :)

Off topic, but here is an article on Steve Baker's site, based around a couple of my photographs of a mongoose. I didn't blip the mongoose because I didn't think the images were any good - seems I was wrong. Have a look.
