Take a fresh stool sample to your veterinary office. Your vet will thoroughly examine the waste and look for signs of worms. Once he gets a confirmation on a specific type of worm, he’ll prescribe medication to get rid of that parasite. Roundworm eggs can survive for months or even years, so it’s important to get medication from your veterinarian to get rid of the worms as well as the eggs.

Ok, now back to your cats. Here’s the good news on the tapeworms: you can buy a tapeworm (doesn’t work for rounds and hookworms) dewormer called Praziquantal over the counter and circumvent a visit to the vet. The bad news is that it’s just as (or more) important to keep the flea count down on your ferals and there’s no easy way to do it. I have witnessed full grown cats die from severe anemia from heavy, chronic flea infestations. At this time, the best longer-acting flea preventatives are topical (there is a safe, long-acting, effective oral medication for dogs but only a short acting product for cats) and I don’t know how you could apply topical products on truly feral cats without confinement and/or sedation. So, go ahead and deworm them but if you noticed weight or hair loss you may need to trap and take them in for a good check up—under sedation of course!
Thanks so much for keeping an eye on these ferals. We, and many shelters have a TNR program (Trap-Neuter-Release) wherein we rely on the community and amazingly dedicated volunteers to identify feral colonies, let us know about them and spay and neuter the bunch. TNR is a critical component to reducing the number of homeless cats and keeping new generations of kittens out of shelters. Bravo to you and everyone who has a hand in TNR. Learn more about our and how you can get involved.

Treatment is the same, regardless of the roundworm involved. There are a number of medications that can be used to treat roundworms, and your vet can help you pick the one right for your cat. Medications will only affect adult roundworms, however, so they need to be repeated to deal with any residual larvae as they mature (e.g., at 2-week intervals). The number of treatments necessary will depend on the age of the cat and the situation, which will be assessed by your vet.
