Ok my cat has been vomited around 4 times so far and I’m not sure what it is, it started as bile from what I looked up and progressed into some sort of mucus that’s yellow and is a solid not liquid he also had a white foam around his mouth after he vomited he casts normally afterward though i don’t know if I should really attach images of the vomit but if you need to I’ll send them

If Tom only vomited one time I would not be that concerned but multiple bouts of vomiting in a short period of time is very concerning. He really needs to be examined by a vet as soon as possible. Vomiting is a very vague symptom and does not point to any one disease process or illness. He needs to be examined and possibly some testing will be needed.

Hi there and thank you for using pet coach to address your concern. The yellow liquid you are seeing is likely bile. This can be seen in vomiting cases. I would recommend having a veterinarian take a look at sienna and have additional tests performed in order to determine what the problem could be. This could be from a systemic infection, disease or intestinal foreign body. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

Hello. Vomiting is not normal. She may have intestinal parasites, or picked up a gastrointestinal infection. If the vomiting continues, you should see your veterinarian to make sure there are no underlying problems here. Thanks for using Petco Pet Education Center, formerly Petcoach.
