Pet's info: Cat | American Longhair | Female | unspayed | 9 months and 28 days old | 10 lbs

I have an almost 10 month old cat that has all the sudden stopped eating and drinking and has diarrhea and also vomiting yellow stuff. She also hides all day long and does nothing but sleep. She also will grow and hiss at people that come into the house like she is going to attck them. I have no money for a vet so I need some home remedies if possible please and thank you!!!

Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). The combination of the signs you described is difficult to treat effectively back home and a clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!

    I would be concerned that Toph's appetite has decreased and she's now vomiting. It could be that she is suffering from a GI illness or may have eaten something rotten, and I will give you a home remedy to try to see if that helps. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
