I know a thread that reads like this would belong in another section of this forum but I'm not discussing its purpose or usefulness to have around. What I do want to do is remind everyone that as of January 1 2017 you will no longer be able to order this product without a veterinarian's prescription so if you don't have it or your running low you may want to get a jug ordered asap. The best price I found was thru Valley Vet Supply, $64.32 to the door.
