Six Month Kitten Vomitting

Question
First off, what a wonderful service you offer.
Long story short (I know that your time is valuable!).
Two weeks ago, we adopted a 6 month old kitten from a rescue shelter.  She had been rescued at 4 months (malnourished, left in a barn, and neglected with 35 other cats and kittens).  She was in the shelter after a stay at the local vet for almost a month.  She spent another month at the rescue shelter regaining her "kittenhood". She is spayed, and has all of her shots. My question (we had one previous cat who we adopted when she was 7, so my experience with kittens is not as keen), is why she has started vomiting.  We adopted her exactly 2 weeks ago and the first few nights she wouldn't eat or drink a thing - understandable I'm sure.  Finally, on the third night she ate and drank, thank goodness!  Three nights ago she vomited after devouring her wet food.  I thought it was because she just ate too fast.  So, I have fed her less and have removed the dish when she became overzealous.  Tonight however, she limited the wet food on her own, and vomited about an hour later.  She is on Technical Adult dry food (at the recommendation of the rescue shelter vet) and I give her half a tin of Fancy Feast wet food at night only (she was on Technical wet at the shelter, but they don't have it at my local pet store, so I bought what our dearly departed cat liked).
Any suggestions would be greatly appreciated.  I really don't know if this is normal or not to vomit so frequently.

Kindest Regards.

Hi Christine,
there are many things that can make a cat vomit, as I am sure you know.
Eating too fast then vomiting is regurgitation, not vomiting. That is what just went in is coming right back out. Vomiting is when they have eaten and hours later they vomit up partially digested food.

So you have had her for two months I am guessing and she just started this. First of all, she needs to be on kitten food, not adult food.
Secondly, Fancy Feast is terrible food which is mostly fats, salts and sugars and is way to rich for her.
Thirdly, garbage food like Technical should only be fed to the mice in the barn.

Now my questions are: was she tested for leukemia, FIV, FIP and anything else at the vets and was she vaccinated when she was tested and spayed? Ok I re-read that and see the vaccinated part. I am guessing she was tested then also.

So that counts out leukemia etc. Now you need to get her on a real diet that will allow her to grow into the gorgeous cat she can be.

Get her off the junk food and buy a bag of Science Diet Kitten Growth in the 4 lb bag and a can of the same food in the wet.

You need to wean her off of one food and onto this food slowly, very slowly. These foods are not kept the same each time they are made, which is a good reason why she is now sick from them.

They used an open formulation which means that what ever is cheap on the docks that day is what goes into the bag. Most of these foods are not even trial fed to see if the can actually sustain life! Formulating food to meet the AAFCO requirements does not mean they have any real value. Food must be fed and tested!! The problem is you can formulate the same food with old shoes, oil and sugar and get the same nutrient profile, but will it sustain life?
I think not.

So get her some real food that has been tested and fed and researched for over 50 yrs by veterinarians. It is not more expensive because she will eventually eat less when her energy needs are met. Right now she is wolfing down food trying to get "a pound of steak protein out of a box of saltine cracker." That is my analogy of the cheap garbage they sell as food out there.

I have been feeding and recommending Science Diet for 28 yrs. I have seen consistent results with it. Once you are close to being done with the old food start mixing in the new over a seven day period. You need to limit her intake to 1/2 cup a day at the moment. She will be hungry (she is anyway) but that way she will be more willing to eat the new food. I have never seen a kitten turn it down. You may have to use the Sensitive Stomach formula on her if she vomits with the new food once she has been on it only. Give her at least 3 weeks to adjust as that is how long it takes for the new food to kick in.

Now if her vomiting gets worse, she could have gastritis so she will need to see a vet right away. If the vomiting lessons and is gone you will know it is the junky food she was eating.

There is also an all natural food for kittens made by Science Diet called Nature's Best. It is a wholesome food with no dyes or preservatives. That might be a better choice for her.

That is what I would do for her first. If, like I said, she keeps vomiting call the vet. Gastritis or constant regurgitation can be a sign of some other illnesses. So if you are worried, call the vet now and change the food after ward.
