My cat left a greenish puddle near litter box. Is it urine or vomit?

This could be very concentrated urine or it could be vomit. If it was urine in that concentrated I would expect it to have some odor to it. I would recommend you monitor your cat for any other signs such as not eating, decreased activity (which I know can be hard to detect in cats), monitor his litter box use as well as for any vomiting. If you see any of those your cat should be examined by a veterinarian. Otherwise if your cat is acting 100% normal it may be OK to just monitor at home for now.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting is sometimes seen with conditions such as inflammatory bowel disease, dietary indiscretion, pancreatitis and chronic kidney disease, among many other conditions. Given Leia's young age and the fact that she is otherwise doing fine, dietary indiscretion appears more likely. It may be something as easy as just changing her diet to something that she can tolerate better. However, an examination by a veterinarian as well as minimal diagnostic data would be needed to rule out more concerning things. You can start by changing her diet to a sensitive stomach type diet. If no improvement, have her examined by a veterinarian to start therapy if needed based on findings. Good luck!

Hello, and thank you for your question! This looks like vomit. Is Stella otherwise acting and eating normally? If so, I would monitor her for now. Offer her smaller meals more frequently, to ensure she is not vomiting due to resting too quickly. If she vomits again in the next 24 hours, or if she seems more lethargic or disinterested in her food, then I would recommend seeking veterinary attention. I hope this helps, and that Stella improves!

If the liquid is urine, then I would be concerned about her kidney function because the brown color could suggest blood in the urine or possibly toxin ingestion. If the liquid is feces then she likely has severe diarrhea that could lead to dehydration. Either way, it is important that you take Willow to a veterinarian to figure out what is going on and to get her treated.

Poor Luna. The dark urine could be due to her being dehydrated, which could be caused by the vomiting. Vomiting could be cause by a GI illness, eating something rotten, a foreign body, or pancreatitis to name a few causes. She may be peeing everywhere the house due to feeling ill. This cannot be treated at home, you need to take her into a vet immediately.

If she only vomited one time and seems perfectly fine then I don't think there is a cause for concern. If the vomiting continues, she has a decreased appetite, or is lethargic then she should be examined by a vet for treatment.

Hello. I am sorry to hear that Smokey isn't feeling well. Vomiting in cats can be due to many reasons including gastric upset, obstructions (something stuck in the gut where it shouldn't be), constipation, pain and stress. Peeing outside the litter box can be due to a medical condition (urinary tract infection, metabolic disease like diabetes, crystals, or interstitial cystitis). Peeing outside the box can also be behavioral if the box isn't cleaned, if there aren't enough litter boxes (# of cats + 1 = # of litter boxes), or if she isn't feeling well and she is trying to tell you. Also, since your cat is unspayed, she is at risk for pyometra (infected uterus). If she is still bright and happy and wanting to play and eat I would try changing the litter, getting another box, and seeing if this behavior goes away. Alternatively you can bring her to a vet and get her urine checked- this is ideal. If she is not bright, not wanting to eat, and the vomiting continues and she continues to not use the litter I would have her seen right away by a veterinarian as there could be something seriously wrong. Also, since she is unspayed, she could be marking, I would recommend getting her spayed once this illness is cleared up. I hope she feels better soon.
