We have been given a set of pens to try and use on some injured wild animals. However, the person who lent them to us has lost the user's manual. Is there a site where I can download it? Thanks.

Thanks for pointing that out. We actually want to try the pens on an African Clawless Otter who was attacked by dogs when she was a pup. As a result, she had spinal trauma and was paralyzed in hindquarters and tail but we are happy to say that she is recovering and can now walk!
