They've apparently been on show for the past couple of months at Barcelona's Museum of Ideas & Inventions (Miba) which opened its doors earlier this year.

It's a seemingly daft but perhaps brilliant idea and while, admittedly, they don't look (to us) especially appetising, most mutts often aren't that fussy about the appearance of what goes into their bowls (or mouths).
What do you think?
