If my cat has one flea and no more and its the first I have ever seen on him after combing what does this mean please? Does he have an infestation?

If you only saw one flea than he probably doesn't have an infestation. The best thing would be to treat him with a monthly flea prevention. Revolution, Frontline, Vectra are good flea prevention products. Talk to your vet about the best product for your cat.
