My kitten has diarrhea, vomiting, tired, losing weight. What's wrong?

I have a kitten that has bad diarrhea, has been vomiting everywhere, and seems more tired along with being clingier towards myself and my husband. I also think she may have lost a little weight, and she was already very thin... I am very worried about her but can't really afford to take her to a vet.

Hi, I'm Dr. Johnson. Thanks for using Petco Pet Education Center, formerly Petcoach! I am very sorry to hear about Annie. My concern for Annie is that with and much vomiting and diarrhea and being so young and small is dehydration. Also young thin animals can get low blood sugar if they aren't eating or holding food down. Causes of vomiting and diarrhea in young kittens are parasites, viruses, eating something that didn't agree with them, foreign bodies, toxins, congenital liver problems, etc. Unfortunately, my recommendation is that you take her to the Veterinarian. There isn't any home remedy. In some areas there are local shelters that have veterinary clinics that can be low cost. I wish you and Annie the best.
