Cat bleeding after litter box since kitten arrived. Could it be worms?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 14 lbs

After my cat is done using the cat litter, he steps out and sometimes has small droplets of blood. Maybe happens once a day. We got a kitten in October, they had contact, used the same litter and water/food. We had brought the kitten in for dewormer and destemper. Could the older cat have worms? Older cat has not had any problems in the past until we got the kitten.

Thanks for using Petco Pet Education Center, formerly Petcoach! This depends largely on if you are referring to drops of blood after defecating or urinating. If it is after defecating, this can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have Rocky evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications depending on the results. Good luck! Hoping for a speedy recovery!
