My gray and white tabby who is 12 and male is vomitting. The stools are solid so there is no reason to believe he has parasites...but this symptom became common after i introduced him to a feral who did have parasites. If any of you have good links to these issues please inform me...oh please dont tell me about a good vet...they are so Clueless as to cat vomitting issues. I am a grown man and just cannot cope with cleaning up cat vomit. Please give some advice. Can he have parasites and not show it in the stool? Thanks
