We adopted a four month old kitten nearly two weeks ago. We noticed immediately that she had terrible gas and soft stool. Fortunately she was good about using the litter box. We assumed she was having trouble with the food changes and tried to wait it out. A week later it was no better so we had a stool sample tested when we brought her in for her well visit. The sample came up positive for coccidia, so we started her and our resident cat on sulfadimethoxine (Albon). Since then her stool has gone from soft to occasionally liquid. She's eating lots of wet food and seems fine, so I'm not concerned about dehydration, but she is making a horrific mess when she uses the litter. It ends up on the floor, walls, etc. Super gross. We are disinfecting one or both bathrooms at least once a day. I know it takes a while for coccidia to resolve entirely (we have ten days of meds), but the cats are now on their fourth day of treatment and we've seen no improvement. Is that normal? Our vet said we'd see improvement in a day or two. Should we be looking for other causes, or do we just need to give it another few days?
