Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach. Toffee could be having diarrhea from things like dietary indiscretion, intestinal worms, inflammatory bowel disease, among many others. I recommend you have her evaluated by your veterinarian so that this can be further assessed. Treatment would be based on the findings. At the very least, they can start Toffee on a medication for diarrhea. Good luck!

Oh no, poor Josey! The excessive drooling is likely due to nausea, which is likely due to the fact he's been vomiting. He could have a severe GI illness, may have eaten something rotten, could have a foreign body, or could have pancreatitis. You can try a home remedy to see if it helps before having to take him into the vet. 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 his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, the diarrhea continues, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

She might have eaten something spoiled that is causing this. withhold food for 8 hours then offer Molly boiled boneless chicken and rice every 6 hours in small portions. if she is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put her back gradually on her normal food.
If she continues vomiting or is not eating, take her to the vet to get treatment.

Poor Eevee! I'm sorry to hear that she's sick! It's very concerning that she has been vomiting overnight, and seems lethargic and painful today. If possible, it would be best to have her seen by an emergency vet today to find out what's wrong and get her started on appropriate treatment.
There are many things that can cause chronic diarrhea and vomiting in a young cat like this, including intestinal parasites, a food allergy or intolerance to something in her diet, an infectious illness of some kind, or even a systemic problem like liver or kidney disease. The emergency vet will likely get her started on IV fluids and medication to help control her vomiting and diarrhea. Your regular vet can do some diagnostic testing once she's feeling a bit better, to help determine what is causing her symptoms and make sure that she's treated for the underlying problem.
