G'day
I have a little problem with Kev the Kangaroo and hope some one can help

you see his tail has dropped off and he just keeps falling all over the place, he used go boing, boing, boing when he jumped but now he just goes jump-thud, jump-thud, jump-thud and he is starting to hurt him self,
All our local vet said was to tie me kangaroo down and not to make a song and dance about it,
can anyone help poor old kev?
