I told twigmouse this was a gift for him, but it's so cute I don't think he'll mind if I share it more widely. (Apologies to Twig if this is not the case, but he should know by now how fickle rats are. :) )
This cute fellow is promoting a brand of cat food, which seems a perfectly honourable profession for a mouse. This is presumably intended to tie in with this commercial, but I don't know if it's currently airing as I don't watch a lot of television anymore.
