Does anyone know if the hedgehogs on the current Abbey advert are real or CGI?

[Doctor Mark]

The current Abbey advert shows two hedgehogs trying to get into a tree stump to make their home. They are either a very well trained pair of hedgehogs, or CGI. To me they look too real to be CGI, but if they are then hats off to whoever made them!!

I don't know but they're absolutely gorgeous.

My guess is they are real hedgehogs but superimposed onto the background scenery with computer magic. They couldn't really get their own red box to climb on now could they?!!
