Hm. Were you able to see what the vomit looks like? What color, what does it consist of, etc? Nala vomits on occasion what is called bile - it's a frothy yellow liquid, and it's Nala's stomach's way of telling me it's empty.

Nala gets fed about 2 & 1/2 cups a day depending on her activity level. She's around 70 lbs.

How is Zeke doing/have you talked to the vet?
