My cat is moaning, unresponsive, and puking white foam. Is it serious?

Unfortunately the only thing you can do is keep Cali quiet and warm, and get her into a vet asap. I would be very concerned based on your description of her symptoms that she has a pyometra. A pyometra is a life threatening infection of the uterus that is fatal without treatment. If she does in fact have a pyometra, she needs to see a vet now. I would call around to see if you can find an ER clinic to take her into, if there is a vet on call to see her, or get her into a vet clinic as soon as they open. I hope this helps!

It sounds as California is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. 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. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

Poor fluffy. It sounds like she is not doing well at all. If she can't walk, that would be an emergency. It may be from weakness or some other neurologic condition. Along with her stomach being hard, I would definitely recommend the emergency clinic. She would need a full exam and some x-rays to start. This will help guide towards the possible diagnosis. Good luck.

BowBow sounds extremely sick, and it's a medical emergency that she is refusing water and food. It may be she has a pyometra, which is an infection of the uterus that is fatal without treatment. It could also be she got into something toxic. This cannot be treated at home, she has to see a vet now. Please take her 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. Best of luck.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Pinkie! Pinkie needs to see a Vet. There is likely an open Emergency hospital in your area. Your Vet, if you call them, should have an answering machine providing emergency clinic numbers. I wouldn't be too sure they are closed Monday. My hospital is open. Causes of vomiting are: intestinal parasites, viral or bacterial infections, foreign body, dietary indiscretion, toxin ingestion, kidney or liver problems, food allergy/intolerance, coughing from asthma. I hope this helps and I wish Pinkie the best!

I don't think this require an emergency visit but i would definitely recommend making a sooner apointment for you vet, preferably before the weekend as this sound like a gastrointestinal condition that will require treatment, possibly a course of antibiotics and a change of food.

Poor Miss Kitty! It sounds like there are two things going on with her, the eye infection and whatever is causing her to vomit. The eye infection is clearly causing her pain and distress because she is pawing at the eye, and she could damage her eye with her claws. The eye is such a delicate and important structure that any problem with it is an emergency as leaving it untreated can lead to vision loss. Her vomiting could be caused by a stomach illness, foreign body, dietary indiscretion, inflammatory bowel disease, and metabolic disease among many other causes. She really needs to see a vet now for both of these issues, and I urge you to take her into a vet immediately to get treated. I hope this helps.
