My cat is vomiting black coffee grounds and acting lethargic. What to do?

Vuk, your kitty needs to be taken to a veterinarian right away. This is an emergency. It is possible that lary was hit by a car, especially if there is fresh blood from the anus. Please find a veterinarian tonight, (even a large animal vet will help) to give fluids, take pain and give at least supportive treatment or euthanize your cat if she is very badly hurt. I am so sorry your cat is so ill.

Dilated pupils can be due to pain, nausea, anxiety, ingestion of toxic substances or neurological conditions. If she is eating and drinking and showing no other signs such as twitching or confusion you could provide plenty of fluids and bland food for 24 hours and monitor for any other signs. If she is otherwise unwell she should be seen as soon as possible

I strongly recommend getting your cat seen by your vet right away. Lethargy is a worrying sign after such an incident and she must continue to eat or she can develop liver disease in a matter of days. There may be more hair that cannot get back out or that may be causing an intestinal blockage. If this is the case, without treatment it can be life-threatening. Your vet will do an exam, x-rays, possibly lab work, and base don these results will be better able to tell you what is wrong and how best to treat it.

These are very serious signs and require urgent vet assessment. It sounds like he has a bleed in the stomach or bowel and i would recommend blood tests to rule out internal complicating factors such as kidney or liver disease as soon as possible

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). 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.

It's really difficult to know for sure without being able to examine her. Given that she hasn't eaten for two days and is lethargic and vomiting, I have to recommend that she be seen by a vet as soon as possible. This could indicate a severe disease, or toxin ingestion. In both cases, her condition can diminish rapidly if not treated soon enough. If you have further questions or need further clarification, then you may consider having an online consult with one of our vets on Petco Pet Education Center, formerly Petcoach. This way, you can send unlimited pictures and have a text conversation with a vet. I hope that helps and Nibbler gets better soon.

This is a medical emergency, and you cannot do anything at home for Kitty. He has to see a vet now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
