Cinnabar Moth Caterpillars?

Observation - Cinnabar Moth Caterpillars?. Description: We saw hundreds, probably thousands of these along the Exeter Canal towpath today. There were dozens on almost every bit of ragwort. I think they're probably Cinnabar moth caterpillars but I'd appreciate confirmation or correction.
