Cat not eating, gagging, lost voice after pest control. What's wrong?

Thank you for submitting your question regarding Kenji. The stress of the new kitten could have started his symptoms, but most of the time a cat will adjust to new circumstances in the amount of time you have described. If it is not stress, he may have contracted an illness from the kitten. I recommend that he sees his veterinarian again or you can consider seeking a second opinion. Bloodwork would be warranted at this point. Cats can actually develop severe liver disease if they go extended periods without eating. I hope this information helps!

Skulls needs to see a vet. There are many reasons that may cause a cat to stop eating but if he does not eat he is at risk for developing hepatitic lipidosis (a disease of the liver when cats go too long without eating). which can be fatal.

Poor Pearl. She doesn't need a vaccination, because these are only meant to be given to healthy pets and at the current moment she isn't considered to be healthy. If she is still vomiting and not eating she likely has an internal illness that needs to be investigated via bloodwork analysis and a urinalysis and treated for directly. Cats can get a condition called hepatic lipidosis (fatty liver) if they go without eating for several days which can make them extremely ill, so I would recommend getting Pearl seen by your local vet right away. Until you can get Pearl in to the vet you can try to offer her small amounts of slightly warmed cans of baby food to provide some nutritional support. I hope your fur baby feels better soon. Take care and best wishes.

This is very concerning and very abnormal. Vomiting in cats can be caused by primary issues with the gastrointestinal tract, dysfunction of the organs, infection, intolerance to a diet, etc. Either way, this is very concerning and KitKat should be seen by a veterinarian ASAP for examination and potential diagnostics.

It sounds like Akira may be sick, and it is very serious when a cat won't eat. If they go long enough without eating (around 72 hours), they will develop a fatty liver. A fatty liver is fatal without treatment, so you want to avoid this. Have her seen by a vet first thing in the morning.

Poor Chico! Lethargy and anorexia can occur with a very wide array of conditions, including FIV, feline leukemia, FIP, pancreatitis, gastrointestinal viruses, etc. When cats stop eating, there is a chance that they can develop hepatic lipidosis (fatty liver disease) as well as becoming dehydrated. Chico sounds quite sick and should be examined by his vet immediately so that any necessary diagnostics and treatments can be started.

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have him 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!
