What can cause my 2 cats to be vomiting almost every day for jsut about 2 weeks now. They eat well, drink well, use the littler box great no diarrhea, they dont fight over food, the bowls are cleaned well, they act normal nothing out of the ordinary. I come home from work at a vet clinic and there will be vomit piles on the floor. Sometimes it is non-digested foor and sometimes its digested food, its not hairballs either. I always see 2 vomit piles and I have a camera in my room to monitor them while away. It seems to happen either really early in the morning like 5-8am or middayish and it is always in diffrenet spots, on the bed, on my desk, on the floor, and under the bed. I think one cat vomits one day and then the other cat vomits the next day it's never both of them at the same day. Their food is Iams proactive health and its been that food for a year now, they get treats and wet food every so often but once they started vomiting I stopped giving them treats thinking it could be that, as well as wet food, and its not either of those things. I'm all out of things I can think of that it could be, they dont eat plants, maybe the only thing i can think of is they ate something like string but they pass stool so they arent blocked on that end. I have an appointment set for both of them on the 2nd of April to get their yearly wellness exams, vaccines and bloodwork done but idk if this is something serious enough to where they need to be seen sooner.
(They also dont have any medical issues but we think one of my cats has mild seasonal asthma)
I'm also a vet tech student so I work at a vet clinic and this just seems odd to me.
