We adopted a 5mo old kitten from a shelter and had her on meow mix for 3 days then switched to natures variety rawboost instance or whatever it's called. I've read if you switch foods to fast they can get diarrhea. She has had it for nearly a week now and was just curious if this does happen how long typically will the fast switch cause diarrhea? Less than two weeks already been to vet twice so before we take her again i was curious about any help here. She was wormed the day we got her by the shelter so probably not that. I'm just wondering if food change can cause diarreah this long or is itaybe just the new food period? Any help would help much appreciated. Thank you.
