Unvaccinated kittens: vomiting, shaking, diarrhea after brother died?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 2 months and 2 days old

Hi, I have 2 male cats that are 2 months old and 3 days ago their brother died and there was a lot of yellowish pus coming from him before he died. They aren’t vaccinated also. My 2 male cats now are Tiger and John. Tiger doesn’t eat, doesn’t drink, shake a lot, vomits a lot (sometimes with pinky blood), has yellowish pus getting out from his anus or something around it I am not really sure. The other one, John, doesn’t vomit but has a strong diarrhea. Please I need help. Thanks

Thank you for submitting your question regarding Tiger and John. I am sorry to hear that they are not feeling well. They will need to see a veterinarian right away. I am concerned they are affected by the same disease that took the life of their litter mate. They will be evaluated and hopefully their disease diagnosed. I am worried they are suffering from feline panleukopenia. Their veterinarian will let you know if this is the case and how best to treat them. In the meantime, try to get them to eat and drink small amounts if possible. I hope this information helps. Good luck!
