My 3-month-old kitten is sick, not eating, and won't play. Should I go to vet?

For sure - this is definitely not normal behavior; as you have said before Cutie is normally playful and active. Unfortunately lethargy is a very general sign of many diseases, and it's unlikely that we will determine the cause of her signs or what to do about this here. I would definitely say that you should be worried, as this has been going on for a few days. Cutie needs to be seen by your vet for an examination and likely some testing, including blood work and possibly x-rays, depending on what other symptoms there are (fever, pain, for example) and the results of the physical exam.

It's very hard to know what is wrong based on these very general symptoms, I would expect a kitten this age to want to play all the time so you are right to be worried, my recommendation would be to have him checked by your vet ASAP

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.

Usually kittens are rather playful at this age, but occasionally some are not very playful. It's good to check that she's not unhealthy though, because this can cause a decrease in activity. Check her gums - see if they are pink or white. If they are white, then he may have anemia. Check the belly - see if it's tucked in or is it round and distended. If it's round and distended, then he may have worms or other intestinal diseases. Most kittens get worms from their mothers, so if he has never had deworming medication, then it would be good to do this. Make sure he is eating and drinking well. Also make sure he doesn't have diarrhea or vomiting. These things can indicate that there is a disease causing him to be less active. The best thing you can do is have a veterinarian take a look at him. They will be able to tell if there is something wrong with him. I hope this helps.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Lethargy and low energy level in such a young kitten is always a concern. This behaviour could be due to fever, pain, intestinal worms and more. Please de-worm your kittens if they have not been dewormed in the last few days. If it does not make any difference, please take him to your local vets for an appointment.

It sounds like poor Olive is sick. Anorexia and lethargy can be signs of many illnesses such as a systemic illness, infection, inflammation, or injury. It's actually quite serious when a cat isn't eating, and I would take her into the vet as soon as possible. The vet can diagnose the cause of her symptoms, and can treat her for it. Please take her into a vet. Best of luck.

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!
