Paraplegic porcupine saved from death by $5 DIY wheelchair made from plumbing
  pipe 
From: MailOnline - 07/03/2014

A paraplegic porcupine is now able to whizz around thanks to a DIY wheelchair
crafted out of plastic plumbing pipes.

The disabled rodent was about to be put down, when a worker at the Piracicaba
Municipal Zoo in Sao Paulo suggested making it a chair similar to the ones
she had seen for dogs on YouTube. It cost less than $5 to make the miniature
buggy, which has a sling to take the weight off the animal's lower body and
wheels in place of its hind legs.
