We treat our cat for worms regularly,last done 2 weeks ago (with treatment from the vets). She's a naturally petite cat but she's looking a bit on the thin side,a bit out of condition. She's eating but just little and often. I've just picked up her poo from outside (she poops in the wood chipping) and it had little tiny worms in it. Does this sound like cat worms or a type maggot from the garden situation?
