Catching up with New Scientist, I was amused to read the following in Feedback:

Not tested on animals

Concern for animal welfare is all very well, but Tom Needham notes that the advertising literature of the manufacturers of Skinner’s dog foods states that ‘no animals are used, or tested on, in any way by our company’. And Karel Tripp feels that the marketers of Arden Grange cat biscuits may also be taking their protestations a bit far. The package states that the contents are ‘not tested on animals’.

What incredible leaps of faith to create pet foods with no idea whether or not your target animals will like the taste.

I suspect this is manufacturers running scared of previous antivivisection campaigns against testing pet food on animals, which always seemed a little strange. Where are they now?
