Thanks, The orange ones had a comet head almost marble sized. The tail was the same as the head, hard & reminded me of something blocking a tube. I thought the ropes may mean colon as have heard people getting ropes from their but these had no trace of poo & were completely bright clean orange. I know she had to have been clogged cause she has been spewing her food up after almost every meal her whole life. Doctors told me it wasn't a big deal if she wasn't bothered by it. And she always said she didn't mind & meant she got to taste the food again. In the last year she has had increasing stomach pain & spewing greater amounts & getting lower belly pain after eating anything. So I have been doing every flush with her. She hates it but I have to insist she does it because it makes sense she needs unclogging. I'm not sure the difference between kidney stones & liver stones ? Do they always get passed through the colon? Many say they pass gravel in the urine?
