Fleas and tapeworms are always a pair!

If they look like sesame seeds or grains of rice(can't really tell the size there) then it's tapeworm. Those are the eggs.

These days, one tablet does the whole job. Get rid of the fleas to prevent recurrence.

Take the eggs or a sample to the vet to make sure, and they can dispense the meds there. Shouldn't have to take kitty in.
