Tortoise-friendly barrier mat

This mat, printed in 98A or softer TPU, keeps other animals from entering my outdoor tortoise enclosure and also cleans debris from the bottom of my tortoise while he enters his house. The spikes on the mat are blunted at the top and are tall enough that most other critters will not be able to comfortably step on it, but will not be injured by it. The tortoise is totally unbothered by it.
