One of my cats vomits a lot from hairballs, even though the vomit just looks like food and liquid. Giving her an inch of laxastat or Laxatone gel every morning, which she licks up, helps enormously. She is FeLV+ but the vomiting is unrelated to that.
Other than that, vomiting can be related to kidney problems, GI problems, cancer, and a host of things that cats with FeLV are more susceptible to, even though FeLV itself does not cause vomiting. Did the vet do blood work? Michelle
