Why is my 4-month-old kitten lethargic, has diarrhea, and arches back?

No, this is not normal. Not eating is very abnormal in young kittens. Most common reasons for the behavior you described is viral disease and internal parasites. Other options are trauma (like he fell and hurt himself) and intestinal obstruction. Milo really needs to be assessed by a veterinarian as soon as possible.

It sounds like he is getting sick. Without additional clinical signs it is hard to say exactly what is causing his lethargy and decreased appetite but he could be starting with a respiratory virus or a gastrointestinal virus. He could also have parasites that need to be treated. If it continues than he should be examined by a vet to determine the cause. Your vet can run lab work to help diagnose and then determine the best way to treat. If he is unvaccinated, please discuss a vaccine plan with your vet once he has recovered from this illness.

Hi. I wouldn't worry about that nail. As far as diarrhea and lethargy, I would get her checked for parasites. Give your veterinarian a call for an appointment and bring a fresh poop sample to be checked. Make sure they keep eating and drinking

Thank you for submitting your question regarding your kitten. I recommend that he sees a veterinarian today. His behavior is worrisome. Even if you are not able to locate his pain, it sounds like he is sore if he is limping. There is a viral disease in kittens that can cause a fever, lameness and ulcers in the mouth. His veterinarian will examine him and determine if this is the case or if he has another problem. I hope this information helps!

Thank you for submitting your question regarding Keanu. I recommend that he sees a veterinarian today as he sounds very sick. Depending on his exam findings, he will likely need bloodwork and fecal testing to determine the cause of his symptoms. Infectious diseases are common in young kittens. Based on these results treatment can be started to help him feel better. I hope this information helps!

Tater is adorable! The signs you are describing can be due to a reaction to a flea/tick preventative or a number of toxins in the environment. It is definitely concerning that Tater is also having diarrhea and loss of appetite/energy as this can be caused by viral and parasitic infections. I recommend having Tater seen by a vet as soon as possible to determine what is going on and begin the appropriate treatment. Your vet will likely recommend a fecal exam and blood work. I hope this helps and that all is well with Tater!

Unfortunately it's illegal for us to recommend any medication without seeing Simba in person. We can't say what is causing his symptoms, so we don't know which medications would be appropriate, and we can't say if they are safe for him or not. You will need to take him into a vet to get treated. I recommend taking him in today. Best of luck.
