Disabled wild bunny in my yard

[BleeckerSt_Girl]

I noticed recently that one young one leaned over to its right when running....the bunny fell over when trying to get away from me, had a hard time righting itself, and then oddly turned its head to the right and back over its side.

Sounds just like e.cuniculi parasite, common in rabbits. Doesn't sound like rabies to me. Cuniculi causes a peculiar head tilt and falling over, loss of balance, spasms. My friend's outdoor cat caught it last year and even though she recovered the poor cat has a permanent head tilt now. I have another friend with an outdoor cat with a weird tilted head and my friend said she thought the cat had been struck by lightning (yeah right) but I am pretty sure it was the work of the very same rabbit parasite. Here's where you can read up on it
Call your vet for more info, I bet they've treated cats with it, though treating a wild rabbit doesn't seem practical.
