Okay so normally Zara does excellent poop, but the past week, with no change in her diet or routine, she's been doing messy ones. Only once in 24hrs and not liquid, but sloppy. No blood. I've tried probiotics and she's up to date with wormer. Today I'm giving only the dry food to see if that helps (she's a good drinker as cats go). She's fine in herself and eating/playing normally. I could take her to the vet Wednesday, but I'm reluctant as she is a very stressable cat who screams the whole time and she seems perfectly happy right now. Anything else I can try before I commit to vet?
