Those blood results could be due to early kidney disease but could also be due to dehydration. Based on the elevated HCT I would guess dehydration. It is a great idea to recheck the values again next month. My recommendation would be to try and increase her water consumption by feeding canned food only . I don't know what kind of food you are feeding but the canned food has a higher water content. Canned food should be easier to digest and may help curb the vomiting. She may have a food allergy causing the problem. Be sure your vet has thoroughly dewormed her. Internal parasites can cause vomiting like this in a young cat. Of course there are many, many other things that can cause vomiting in cats and it may take quite a bit of testing to figure it out. If she has not been tested for feline leukemia (FeLV) or feline aids (FIV) I suggest you have those tests run as well. Hope this helps.
