Calling these weasel words...

... would be an insult to weasels everywhere:

The Home Retail Group, of which Argos and Homebase are members, said it was committed to being a responsible retailer. A statement said: "The RSCPA has advised that it has no current recommendation for the size of a hutch for a single rabbit. In our autumn/winter catalogue we do make it clear that hutches should be used in conjunction with a run, we will be amending the website to that effect. We also offer a discount on a run if purchased in conjunction with selected rabbit hutches."

One reason why there is no official recommendation for the size of hutch for a single rabbit is that the RSPCA advises that rabbits should not be kept on their own!
