Poor Twilight! It sounds like he is feeling terrible. Just like people, there are many conditions that can make pets feel sick. This could range from a viral infection to kidney disease. Also like us, diseases are best addressed early and this may result in a better prognosis. I recommend to have him examined by the veterinarian today. The doctor will need to learn the underlying cause in order to give appropriate treatment. Bring in a stool sample in case the doctor needs to test it. Cats hide their illnesses until they are advanced so he has likely been sick longer than you may realize. Cats also won't eat if they can't smell the food and the mucus is likely preventing that. He will need to be treated in order to get the mucus to clear up so that he will hopefully start eating again. Dehydration can also set in quickly so have him examined. I hope Twilight starts feeling better quickly! Please feel free to post any additional questions!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This is a classic sign of nausea. Loss of appetite, diarrhea and nausea can be observed with many conditions such as gastroenteritis, dietary indiscretion, pancreatitis, among many other possibilities. I am concerned that he could be becoming dehydrated. I recommend that you have Aslan evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

    Poor guy! It sounds like you should take Mr Meows-a-Lot in to see a veterinarian today as this sounds like an emergency. If he has a fever and is vomiting, I am very concerned that he may get significantly worse if you wait. Aside from an exam, he likely needs to have some blood work done to see if anything is abnormal that could indicate why he is so sick, as well as IV fluids. Cats usually will lick their lips a lot if they are nauseous, so he likely needs some anti-nausea medication as well.

    They often act like this when they are coming down with an illness. In the next day or two he may have signs of an upper respiratory infection (nasal/ocular discharge and sneezing), or gastrointestinal problems (vomiting or diarrhea). For more information about these conditions, I recommend you read the information at the links below. http://www.wikihow.com/Help-Your-Cat-Breathe-Easier https://www.petcoach.co/article/diarrhea-vomiting-in-cats-when-to-call-your-veterinarian/ It's good that he's drinking, but I would worry if he is not eating for longer than 24 hours. In this case you can try hand-feeding him some wet food by putting a little in his mouth at a time. Please note that the vet will not neuter him if he is sick, so if he is not better by the appointment time, then it would be best to take him for an exam by a vet instead. I hope that helps and Wilson gets better soon.
