Why is my cat's mouth open, smelly, lethargic, and not eating?

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.

Hello. It sounds like your poor kitty is unwell. This could be anything from an upper respiratory infection to some dental issues, such as an infected or abscessed tooth. Most of these things are just too complicated to try & deal with at home, especially if antibiotics are needed. It is always best to have these things looked at as soon as possible before any symptoms worsen. Thanks for using Petco Pet Education Center, formerly Petcoach.

Thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry to hear that she is not feeling well. This discharge could be coming primarily from the mouth or any of the associated anatomic structures and it is not possible to know exactly without an examination. This could certainly be due to an infection for example. It does appear that she is uncomfortable. How this is managed really depends on what actually is going on. For that reason, I highly recommend that you have her evaluated by a veterinarian for further assessment and treatment. They would be able to diagnose this and proceed with therapy accordingly. Best of luck!

Thank you for submitting your question regarding Sam. I recommend that he sees an emergency veterinarian today. He needs to be examined. If there is a smell coming from his mouth, I worry that he has a wound. If he is painful, then he will not open his mouth. There are also other causes of not being able to use the mouth properly such as infectious and inflammatory conditions. The veterinarian will examine him and may recommend some testing. Based on these results, treatment can be started to help him feel better. I worry that he will become dehydrated from not eating and drinking properly. This may need to be addressed as well. I hope this information helps!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Coco is nauseated from something, it is difficult to say for sure the cause just based on the symptoms. Coco may have a systemic disease or infection going on that needs antibiotic therapy. I would recommend having a veterinarian examine Coco so that the most appropriate diagnostic and treatment recommendations can be made. I would recommend having his blood tested to be on the safe side as well. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hello. Roxie probably has some significant dental disease, & this is often accompanied by a condition called stomatitis, which is a chronic irritation of the tissues within the mouth. The exact cause is unknown, but it is often multifactorial involving bacterial infections & an abnormal immune system. Your history definitely points to this, but your veterinarian needs to confirm things. Treatment can be relatively simple with antibiotics & periodic use of steroids. Most important will be an initial examination & cleaning of the teeth under general anesthesia. In the worse case, all the teeth may need to be removed because they present an ever presence of antigens in the mouth that promote the painful lesions. The next step is to make an appointment with your veterinarian as soon as possible to start to address Roxie's problems. Good luck & thanks for using Petco Pet Education Center, formerly Petcoach.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Smokey. Poor boy! I agree, it does sounds like he has a dental problem, and it could be an abscess. It's pretty serious that he's not eating much, and he is likely in a lot of pain. I think it's best you take him into a vet now. I hope this helps!
