Agree, it's important to know how much the rabbit weighs before figuring the dosage. You don't want to overdose with Ivomec. 1/4cc may be about right for a flemish adult. I'm not good with metric stuff so I had it converted to something easier for me. I use .018cc per pound for the 1% solution. For a 10 lb rabbit it comes to .18cc. The one time we had to treat for mites most of our rabbits only needed 2 treatments and a couple got the third one.
