Still has roundworms.

Species: Cat
Breed: DSH
Age: 1-2 years
My 2-year-old cat, Oliver, has been having a problem with roundworms. He was born outside and I adopted him from a shelter. Now he is strictly an indoor only cat, and I keep his litter box and my home very clean.

A few months after I adopted him in January 2010, he vomited out 3 roundworms. I immediately got him a Drontal treatment (two pills within three weeks) and then brought in a stool sample and it tested negative for eggs/parasites. 3-4 months later, the same thing happened; Oliver vomited out worms, he got dewormed, and then tested negative. I cleaned his litter box with bleach and threw away all his toys he carried around in his mouth.

A week ago, Oliver vomited out roundworms again! This is the third time that this has happened. I don't understand why he keeps vomiting out worms after his stool tests negative. Could you tell me what's going on with poor Oliver? I'm not sure if I should give him Revolution for the rest of his life or keep deworming him every few months.

Online vet, Dr. Marie

Dr. Marie replied:

A cat can still have a negative stool sample even though they have parasites. This is because some parasites like roundworms can go through a stage where they don't lay eggs.

While Drontal is a good dewormer, if this were my case I would likely be using a different dewormer (such as milbemax) every 2 weeks for about 8 treatments, and then every 3 months.

Revolution is ok for roundworms but not the greatest.
