I went mad for one of these with my first rabbit many years ago,i was only about 12, i got home put Sandy in it strate away took him in the garden he went under a bush so i waited he hopped out not in the harness, when i looked he had chewed through the harness and run off i had only had it home about 10 mins, i did try to sew it but i dont think he ever went in it again xxx
