Easiest way to administer is squirt the dosage onto a basil leaf or similar, then roll it up, works a treat and no stressed bunny or risk of being bitten.
This is the 3rd time I am nursing my rabbit through head tilt. You need to dose for a full month if they are ill, but just the 9 days if using as a 'preventative'. I squeeze the correct doseage onto a dandelion leaf which is the only way she will take it! My other rabbit loves the stuff and will take it straight from the tube!!! I will be dosing twice per year as recommended on both rabbits after this 3rd attack.
I started using this last year after we lost a bunny to E.Cunicul. The parasite struck so fast that he died within 4 hours of getting to the vets. Thankfully our little girl bunny was ok and not infected. I put it on food sometimes and give directly at others to make it less stressful for the pets. Also this website is by far cheaper than buying from vets or other local outlets. I just order it when needed with a larger order to avoid postage cost.
I have five rabbits. I find using it very easy on all of them and they are not all well behaved. The nine day course is a bit of a pain, but if you know that they are covered against head droop it is a small inconvenience.
It seems to work, but it's tricky to administer and a pain to have to do it for 9 consecutive days. It definitely took two of us - one to hold the rabbit and the other to syringe down the throat. We also couldn't have read the instructions properly because we didn't realise that there was a measure, which automatically stopped the syringe at the right dosage for each day. Without this in place, it's very difficult to get the dosage right. I have since heard other rabbits owners say that they put it on a tasty leaf that their rabbit loves and roll it up - whether this works or not, I don't know.
