Emu, thats not a lone case. My cousin when he was little was bullied because he has a wonky eye. They did the same thing to his rabbit and left the head in the hutch.
So in all honesty, no I dont think its the lowest of the low. Did the thieves know she was autistic> and has it definitely been stolen, we had a guinea pig escape from it hutch. Not really sure how but think I may have been at fault somewhere, turned up later in the week and most of its hair and fallen out.
