Is this a wren?

Question

Hi there seems to be a nest in our shrub and young birds have been running on the ground. Is it too early for fledgings? Also how long will I need to keep my cats in as one of them nearly caught one today. Thanks.

Don't think it's a wren -- maybe a thrush? If there are fledglings on the ground you should be able to spot the parent nearby with a bit of patience. 
It's absolutely the time of year. They'll stick around on the ground for a few days, maybe a week, with the parent in close attendance to ward off cats/gulls/magpies/hawks/whatever else lives nearby. Once they're flying with confidence they'll start to range farther.

Looks like a young Thrush to me

No, but it is probably a young song thrush.
