What causes a cat to be weak, lose weight, sleep, gag, and be clingy?

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!

Sudden weight loss is always a very big warning light that should not be taken lightly, it's usually a sign of an internal disease that needs to be investigated, i strongly recommend taking him to the vet in order to get it checked, he will need to have a blood test done and possibly an xray as well in order to attempt to diagnose the reason for these symptoms.

Poor Garfield. At age 17 that is an awful lot going on and I'd be worried there is an underlying issue such as kidney or organ failure, disease, etc. Since he's so old and is having so many symptoms, it's best to bring him to your vet ASAP. They will likely want to run a few tests such as bloodwork or an X-ray to check his organ function, etc. If you can, bringing in urine or stool samples can also help with any testing and help streamline the process. Until you can get the vet, keeping him as comfortable as possible and keeping his eyes and nose clear with a clean washcloth can help. Some cats also do better eating if they can smell the food, so warming up his food or adding some boiled chicken that is smelly may encourage him to eat a little until you can be seen.

Kermit is experiencing very general symptoms of disease, these symptoms could fit almost any internal condition, maybe he is suffering from nausea due to a gastrointestinal disease and maybe he is in pain, from the symptoms described it's very hard to know. i would recommend taking him to the vet as soon as possible in order to get him checked, if he doesn't show any other obvious symptoms during the examination, a blood test and possibly an ultrasound will be needed in order to try and find out what is wrong with Kermit.

Tommy is experiencing very general symptoms of disease, these symptoms could fit almost any internal condition, maybe he is suffering from nausea due to a gastrointestinal disease and maybe he is in pain, from the symptoms described it's very hard to know. i would recommend taking him to the vet as soon as possible in order to get him checked, if he doesn't show any other obvious symptoms during the examination, a blood test and possibly an ultrasound will be needed in order to try and find out what is wrong with Tommy.

I am very sorry to hear about Skylee. Unfortunately in an older cat there are a large number of conditions which could cause lethargy, nausea, and anorexia. I would strongly recommend taking him in to see the veterinarian as soon as possible. A good physical examination may help them get a better idea of possible causes. Most likely they will want to do bloodwork to check for signs of kidney disease, liver disease, infection, or anemia. They may recommend x-rays depending on his examination and history. It is best to have older pets acting ill in this way checked out soon so that if there is a serious disease we can start treatment as quickly as possible.

It sounds as Mini is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
