We have an 8 month old spayed female who is on some sort of weird cycle where every 3-4 weeks she is vomiting and not eating or drinking any water. This goes on for 2-3 days and then she is back to normal. We have taken her to the vet who thought it was some sort of liver bacteria and gave her meds to rid her of it. During the three weeks med treatment she was fine but a week later it was back to vomiting and not eating. My wife noticed some blood in her urine as well on this last bout. Unfortunately I am finishing up a tour in AFG and cant really help my wife so she is going at it alone. Of course she is taking her to the vet again, but I wanted to see if anyone here had similar issues.
