Hedgehog
The hedgehog, despite its spiny exterior, represents one of Britain's most approachable wild mammals. Wildlife rehabilitation centres regularly handle hedgehogs, and the creatures can become accustomed to human presence within their garden territories. Supplementary feeding with cat biscuits has become a suburban ritual.
The hedgehog's nocturnal snuffling, while initially alarming to those unfamiliar with the sound, is widely considered endearing. The creatures have become symbols of wildlife-friendly gardening, their presence indicating a healthy local ecosystem.
Volcano
Approaching an active volcano requires specialised equipment, training, and a certain disregard for personal safety. Volcanologists perform essential work in monitoring volcanic activity, but even they maintain respectful distances from active vents. Tourism industries have developed around volcanoes, though visitors typically view from observation points several kilometres distant.
The volcano cannot be stroked, fed cat food, or invited into one's garden. Its sole concession to approachability is occasional dormancy, during which humans may walk upon its slopes in relative safety.
VERDICT
The hedgehog achieves complete dominance in this category through the simple virtue of not being lethal to touch. One may offer a hedgehog a dish of water on a warm evening. Offering a volcano anything results only in the rapid vaporisation of the offering. The hedgehog wins by approximately 1,200 degrees Celsius.
