I won't try and make any assumptions here partner -- BUT, did you put the Cidr's n the Vagina -- or like it sounds -- Rectally?
The only way that Cidr will fall out when she deficates is if you put in the wrong hole?? I certainly hope for your sake that is not the case?
As mentioned, inserted correctly, the blue string will be bent DOWNWARDS, and will only show on cows meybe 1/2 it's length tops. I have cut some off of the hfrs, so as they don't chew on them after insertion and pull them out -- they get goofy at times.
I think we are all wondering about the placement -- updates that and certainly we can and will help you out!
