Roundworms do not require an intermediate host to spread from cat to cat, but can be transmitted by ingesting the eggs that are passed in the feces of an infected cat. Hookworms are one of the most significant intestinal parasites of the cat. The hookworm is approximately ½ to 1" (1-2 cm) long.
How easy is it for cats to spread worms?
If you have a cat, the odds of your kitty contracting an intestinal parasite is very good. It would be more shocking if a cat went its whole life never contracting worms. Both indoor cats and outdoor cats are at risk of contracting worms.
Should I treat both cats if one has worms?
It is always safest to test all household pet members for parasites (fecal or stool sample) OR treat all household pet members as if they are infected. Treatment may be in the form of liquid, pill, powder or topical medication.
