Thank you for submitting your question regarding Twiggy. If her symptoms continue, she will need to see her veterinarian. She could have an intestinal infection or inflammation. If this is not the case, it could be a reaction to something in her diet or a disease such as pancreatitis or an overactive thyroid gland. Based on her exam findings, her veterinarian may recommend laboratory tests to determine the best course of treatment. In the meantime, encourage her to drink water so that she does not become dehydrated. I hope this information helps!

    Unfortunately there is a huge list of problems that can cause vomiting and diarrhea in cats. Commonly we see parasites, bacterial infections, viral infections, and even intestinal obstructions. I would highly encourage you to have him evaluated by your veterinarian as soon as possible. They may recommend an x-ray or blood work to help determine the diagnosis and best treatment plan. Best of luck and thank you for using Pet Coach.

    Your English is just fine, and you are right to be concerned! Vomiting and diarrhea could be caused by a number of things, including parasites, diet changes, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, food sensitivity/allergy, decreased pancreatic function, or a mass/growth in the gastrointestinal tract. Please make an appointment to have Hope seen by a veterinarian as soon as possible to allow for diagnosis and treatment.

    Thank you for using Petco Pet Education Center, formerly Petcoach! Sidney should definitely be seen by a vet as soon as possible. The signs you are describing can be caused by pancreatitis, severe intestinal parasitism, intestinal cancer or inflammation, as well as ingestion of something toxin/something Sidney should not have gotten into. Your vet can perform bloodwork, x-rays, and an abdominal ultrasound if necessary to determine what is going on. I hope this helps and that Sidney feels better soon!
