Pet's info: Cat | American Shorthair | Female | unspayed

My kitten accidentally ate adult cat food and started vomiting and having diarrhea ever since. I took away her food and water and gave her Pedialyte, but now I found blood in her stool and she is very weak. She refuses to eat or drink anything. Please help.

It sounds as Selina is suffering from a gastrointestinal condition, possibly an infection. it might not be related to the adult food she ate, the blood and complete lack of appetite is very worrying. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

    Poor Roma! If she is always getting into stuff, it could be that she has eaten something that has upset her stomach or caused an intestinal blockage. Because she is vomiting and having blood in her stool, I do recommend a visit with the vet as soon as possible. The vet can do x-rays to see if she does have an intestinal blockage, as well as examine her and discuss treatment options for her. I hope this helps, good luck!
