Kittens are susceptible to many different infections, both viral & bacterial. A heavy parasite burden from coccidia, or roundworms can also wear a kitten down & leave it weak. Pascal is too young & small to try & fight this off on his own. He needs to be seen by a veterinarian as soon as possible. If you can not have him seen tonight or tomorrow, pick up some Nutrical from Petco tomorrow, & try to give him small amount frequently throughout the day. This is a high calorie supplement to hopefully keep his energy up. Then please try to have him seen by your veterinarian as early as possible on Monday. I hope he does better soon.

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting, lethargy and decreased appetite can occur from many conditions such as foreign body ingestion and obstruction, pancreatitis, gastroenteritis, dietary indiscretion, among other possibilities. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. This will likely require bloodwork and abdominal imaging in terms of diagnostics. Treatment would be based on findings. At the very least your veterinarian could start him on medications to make him feel better. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!

Why is my 4-week-old kitten lethargic, vomiting, and not urinating?

Hello. I am a little concerned about your kitten because at 4 weeks of age she should be a little fireball & not require stimulation to move her bowels. She should also be eating a canned kitten food with a little replacement milk mixed in. If she has not been dewormed, this would be a priority as intestinal parasites like roundworms can make a kitten pretty weak. She may also be a little dehydrated if you have not seen her urinate. I truly hope you can have her seen by a veterinarian soon. Little babies like this can be pretty fragile. Thank you for using Petco Pet Education Center, formerly Petcoach.

Why is my 3-month-old kitten lethargic, weak, vomiting, and has fleas?

Hello. You should take the kitten in to be evaluated as soon as possible. Fleas do carry diseases that can infect cats & kittens, & if there are enough fleas, can actually cause anemia. If the kitten has not been wormed, then the presence of intestinal parasites such as roundworms can weaken a kitten further. Other infections/conditions are possible, so I do hope you can have him evaluated by your veterinarian soon. Thanks for using Petco Pet Education Center, formerly Petcoach.

Why is my 4-month-old kitten vomiting and sleepy after eating?

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! This could be related to some degree of gastroenteritis or upset stomach. This would be the best case scenario. I recommend that you continue to monitor Whiskers closely for now. Have water available at all times to try to avoid dehydration. If no improvement is seen in the next 24 hours or he develops more vomiting and becomes more lethargic, have Whiskers evaluated by your veterinarian for further assessment and treatment based on findings. Good luck!

Why is my new kitten lethargic, twitching after dewormer and shots?

He needs to be seen by a veterinarian for a wellness exam. He may not be able to poop and may be constipated, or he had so many worms that all the dead worms are making him ill. Keep him warm, entice him to drink water, and should he deteriorate he needs to be seen at a petER tonight.

Why is my kitten lethargic, not eating, barely drinking, and warm?

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. Poor Gypsy has picked up an infection, either bacterial or viral. It is also possibly he has gotten into a fight with another cat & has sustained a bite which in now infected. Cats can not go very long without eating. After just 3 days we can see damage to the liver. Gypsy needs to see a veterinarian tomorrow to see if he needs some fluids & antibiotics to help get well & feel better.

My cat can't walk, eat, or drink. What's wrong and what should I do?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! So sorry to hear about Jack. Cute name. He sounds very weak especially if he is not eating or drinking. Many things could be going on such as pain, intestinal worms, fever from many sources - infection, inflammation, etc. Kittens commonly develop upper respiratory infections due to viruses but can then develop secondary bacterial infections. It's best to take him to your veterinarian right away so they can perform a physical exam including his vitals to see if he has a fever. Once they perform that, they can advise fecal tests, blood tests, or x-rays to help them determine what is causing him problems. I hope Jack gets well soon.

My cat is lethargic, wobbly, and not playing. What's going on?

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!
