Why are my cats vomiting blood, weak, refusing food, and dying?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 year and 4 months old

Hi, I really need your help. My cats are getting sick. They started vomiting with blood(bad smell), getting weak, and refusing food. Body temp is warm to the touch. They live in a large enclosed house cat. In total, they are 17 cats in there but 5 have already died because of this sickness. They were given oral doxycyclin and immunol liquid by the local vet but it is not working. RBC count is also low during lab test of one of the cats that died. Please what could this be.

There is a chance given the symptoms that this could be panleucopaenia, a highly contagious viral gastroenteritis in cats related to parvo virus in dogs. I would recommend testing at least one affected cat as if positive vaccines can help protect the others. Fluids and anti nausea medications can help
