NOTE: NOT FOR THE VERY SENSITIVE OR SQUEAMISH
You know,Bunty, I wondered why my bunnies were staggering around the house and yard, arm and arm? Hehehehehe!
I recommend 1/2 - 1 tsp per gallon of drinking water, but I, myself, nolonger measure it. Like Grandma and her recipes of a,"pinchof this, a pinch of that, and a handful of this," I just "eyeball" itand add vanilla until it "looks" right to me. While it maycontain alcohol, I would seriously doubt the quantity involved over theperiod of time it is ingested presents a health problem. Youdo bring up a point I never considered over these many years, though,and, obviously worthy of merit. Illustrates perfectly howvaluable forums like thiscan be to everyone.
Batbunny, the practice of administering vanilla extract in the drinkingwater is to reduce the probability of the rabbits' contracting FlyStrike and/or Warbles. In the former, flies lay eggs in theexcrement that may exist on the nether parts of a bunny with a dirtybum, due to excess fur in the genital region, stoutness of the bunpreventing it from cleaning the area adequately, or a diarrheacondition leaving the area soiled. The eggs hatch intomaggots and eat, not only the excrement, but when that is gone, beginto eat the flesh of the rabbit! Frequently, it may gounnoticed, until too much damage is done, and the bun succumbs to ahorrible death.
Warbles are caused by a specific vector, called a BotFly. The Bot Fly lays a single egg somewhere near or ona rabbit, anywhere, but a dirty bum is a good a place asany. The single larvae(warble) burrows underneath the skin,usually starting in a natural orifice,in order to continueits metamorphosis into an adult by feeding on internal fluids of itshost. Its location is often indicated by a cyst-like noduleon the skin, with a tiny, dark colored "air hole" on thecyst. The major problem presented by the larvae is that itinadvertently produces toxins that may be fatal to the rabbit, beforethe larvae becomes and adult and leaves its host. I've readthat one can cover the air hole with some substance like a cream,thereby forcing the larvae to poke up its head looking or air,whereupon one can pluck it off with a tweezers. Vets,I assume, could lance it free. The Bot fly larvaeis about the size of your pinkie nail, if memory serves me correctly,and is not a major menace in all parts of the country or the world.
The vanilla in the drinking water apparently produces an odor in thefecal matter and urine of the rabbit that is repugnant to flies of anykind, thereby reducing the probability of developing Fly Strike orWarbles. Since incorporating its use into my rabbithusbandry, I've noticed a significant decrease in the number of fliesin and about our outside hutches.
Even if one chooses to not incorporate vanilla into the drinking water,both conditions noted above are more than enough reason tovisually and manually inspect your rabbit very closely on a regular andtimely basis. The addition of vanilla in the drinking watermay increase consumption, so watch the water levels of your buns'bottles afterwards.
