Question
I found what I think is a leech on the neck of a rabbit it is about 1 to 1.5 inches long and as big as a thumb.  I have pictures. There are about 9 "rings" around it and it looks hairy.

Answer
Dear David,

Unless you live near a very wet area, it is really unlikely that this is a leech.  Leeches also do not have visible bristles.  What I believe you are seeing is a botfly maggot that has emerged from its cyst on the rabbit, in preparation for dropping off to pupate.

You can see pictures of botfly maggots here:

(scroll down to "rodent botfly maggot) to compare with what you see.

I would get the rabbit to a good rabbit vet:

www.rabbit.org/vets

so the vet can check all over to be sure there are no other warbles (botfly cysts) that have larvae in them, requiring removal.  If the cyst on the bunny's neck is infected, it will need treatment.  

If you are sure what you have is *not* a botfly larva, then you can let me know where to see the pictures, or send them to me privately.

Hope this helps.

Dana
