Most of this stuff can be found online if youcannot locate it in your area. Sometimes, I find it worth theexpense of shipping and the wait to buy online instead of knockingmyself out on a quest to find a product locally. Figure mypeace of mind is worth that.
I've ordered papain and bromelain powder online. They are theactive ingredients in papaya and pineapple(enzymes) that break down themucus holding fur balls together, permitting the fur to beeliminated. I used to dissolve them in the buns' drinkingwater in order to insure they were getting a fur block treatment thatentailed no extra sugar, as is often found in the pill form.
While on vacation last summer, I didn't want to saddle the bunny sitterwith that extra chore, so stopped giving them the powder.They still continued to eliminate "stringers" without thetreatment. The Missus often says I tend to overkill andthought my feeding them papain and bromelain fell into that category,so, I opted to discontinue the inconclusive experiment.
The powders, from a health food company were about $22-$25.00 per 100gram bottle...expensive, but I thought they might be cost effectiveover the long run if administered to the drinking water. Iadministered 1/8-1/4 tsp per 32 oz water bottle, which was therecommended dosage per day for a human.
I can't say as how the treatment worked, or did not work.
