Why are my new indoor feral kittens sick, vomiting, and lethargic?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | unneutered | 6 months and 1 day old | 8 lbs

I have 2 ferral cats I took in. They have been doing excelent and I nabbed 2 more of the next litter and they are doing excellent. They have been inside 1 month. They are Karats. The oldest are males and the young ones female. The male got sick then 4 days later the other male did. Their symptoms are lethargy, lack of eating/drinking and now throwing up. The only new difference is scented litter instead of non. The vomit is watery. I treated ea for hair balls and feed them food for hairballs.

I recommend to have the kittens examined by the veterinarian with in the next day. Many times these kittens will be played with internal and external parasites. Changes in diet and viral infections are also possible causes. There are a few types of parasites which can be transmitted to humans so it is very important to make sure they are treated appropriately to keep the humans in the household safe. I also recommend to look into a trap neuter release program for the mother cat to help control the population. One female cat can have almost 30 kittens in a year and this can lead to disease outbreaks and sanitation concerns. Best of luck.
