Thank you both so much for helping, in western australia nobody knows anything about guinea pigs, most vets refuse to even treat them. I have been so weighed down with sadness these past few months, I'm just so miserable for her. I thought her pain while urinating was lessoning, because she stopped sqweeking (she generally only sqweeks once at the end). Then four days ago she had an attack of sqweeking and urinating over and over, she just lay still and I laid on the floor with her for an hour stroking her and crying. Her eyes glazed over and went grey. At one point I thought she was dead. It was awful.I decided to not let her die on the ground and I scooped her up and hugged her. After the hug she got back to how she was before the attack (standing up for food ect) The only thing that I thought could have triggered that was I stopped giving her poo soup for two days (because she hates it so much -- i don't blame her), now I'm afraid to miss a dose incase that's what caused it. She is still curious and sometimes even jumps on her igloo. Is metacam better than tramal? she was on it once before, but with every thing shes been on I can't remember how she reacted. Will she be able to safely remain on that for years? She was seeing a guinea pig 'specialist' and was put on some new mite killer for guineas and when that didn't work ivermectin. After the ivermectin she stopped scratching and for weeks latter only now pulls at her fur. I was flushing her bladder with 40ml a day, but have lessened it to about 5ml, because for some reason it seemed to make it worse. I also only buy her very low calcium foods and give her lots of hay and a tiny amount of pellets.I haven't had cats or dogs, and after this don't see myself having pets again, I can't take the emotional toll. I will look up those pills to coat her bladder, hopefully they have them in Western Australia - thank you!
