A quick search on Google shows a lot of results for Libdems Goldfish, mostly linking to people commenting on blogs about a policy passed back in 2003 (I believe).
More suprising was that these comments are still apearing, even after the Pet welfare act was passed, and today becomes law.

Under the act the minimum age for buying a pet will rise from 12 to 16 and under-16s will not be allowed to win a pet as a prize.

Which was what we were saying all along, wasn’t it?
