Hello - I am Dr. Matt - I would be glad to help you with your question.

Just to clarify - Did Little Tom throw up two different worms or just one that was white and reddish brown?

Was the white worm flat or round?

Does he go outside?

Heartworms are usually round and white in color and when present, live in the heart and blood vessels that attach to the lungs. Because of this, vomiting up a heartworm is not usually possible. Other worms that could be vomited up are roundworms and stomach worms. These are usually white though some can have a slight brown color. Roundworms are usually quite long.

Based on the picture - this looks like a tapeworm based on the segmented body that it has. Tapeworms come from ingesting rodents or from ingesting fleas on the fur. I would definitely check him to make sure that he does not have any fleas. If he does then using a monthly preventive such as Frontline Plus or Revolution is recommended. I would also recommend treating him with a dewormer then contains Praziquantel. This is usually available from your vet though let me check to see if it can be purchased over the counter.

Here is an example of a dewormer that can be purchased for the tapeworms.

Hope this helps - please feel free to reply if you have any questions - Thank you!

Thank you hope my other cats can't get it
Expert:  Dr. Matt replied 4 months ago.

Tapeworms are not contagious to other cats directly. If one of the other cats ingests a flea or unfortunately a rodent then they could get tapeworms also. Might not be a bad idea to treat all of your cats though just to be sure.
