I enjoy Tim Dowling’s columns – he is funny. But I have a quibble about him giving his tortoise lettuce, which has virtually no nutritional value (Saturday magazine, 8 November).
I worked as a records keeper at a zoo for more than 20 years, and one of my duties was keeping track of tortoises brought in by people who could no longer care for them. We were also the meeting place for a turtle and tortoise club, and offered information on their dietary needs.
