Paignton Zoo is a very large and impressive complex. They take trouble over animal welfare and have created some sizeable enclosures. The only problem is that they're so vast, you have trouble actually spotting the animals.
Mrs W was reading the Zoo's guidebook after the event and told me that giraffes have particularly high blood pressure. I wondered whether this made them more prone to stroke and heart disease. They also sleep for only 20 minutes a day. A bit like Maggie Thatcher used to.
