Lexie can't seem to tolerate any treats or wet food whatsoever - it immediately gives her diarrhea, so she's been on strictly dry food since then (MaxCat Adult), but still seems to have soft stools fairly often (they range from hard to very soft), and smell like there's no tomorrow - i'm having to wipe her bum everyday due to remaining bits. What could cause this? Should i try switching foods? What other alternatives could i use as treats?? She's been dewormed a month ago and is also on advantage flea treatment (rescued as stray).
