Why is my cat not eating, hacking, and lethargic after a new kitten?

Updated On September 23rd, 2025

Pet's info: Cat | Ocicat | Male | neutered | 1 year and 3 months old | 12.6 lbs

Ever since I got a new kitten my 1 year old ocicat has been eating very little. Over a week progressively started hacking but nothing is coming out. Eventually he lost his voice completely and can hardly talk. I has been 9 days and I think he's getting weak from not eating because he's very lethargic. I took him to the vet and they said that this may be because of the new kitten. I separated them completely after 4 days.

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!
