I adopted a three-month-old kitten from the shelter last week, and she has had soft, bloody stool since I brought her home. She is FELV/FIV negative, energetic, eats (the same food as at the shelter) and drinks well. On day 2, I gave a sample of her stool to the vet, and they could detect no parasites. She had been dewormed x3 at the shelter with Pyrantel. I suspected coccidia, and the vet agreed and prescribed Albon for 7 days. When there was no symptomatic improvement after 3 days of Albon, I took her to the vet. He palpated her stomach, and she showed no signs of discomfort to suggest a foreign object (and she really hasn't had a chance to eat anything unusual). The vet prescribed Panacur for 3 days while continuing the Albon. She had her last dose of Panacur today and will have the last dose of Albon tomorrow, but she still has soft, bloody stool. Does anyone know what the time from treatment with these meds to symptomatic relief is supposed to be? Does it take multiple courses to treat the harder bugs like coccidia/giardia/trich? At what point does it make sense to stop treating as if it is zoonotic, and is it possible that the courses of meds, themselves are upsetting her GI tract? Has anybody had a similar experience?
