We have four feral cats and we usually treat them with paragard as they usually fetch worms. This product works perfect, lately, only had to retreat 3 cats so far and saved one of the feral cats from dying from parasite infestation.
having used for straight four years, can say that it is quite effective and works well.
no more worm infections. has controlled diarrhea due to worms.
he was suffering badly due to those worms. giving the wormer really relaxed her from the pain.
This product did help my cat with worm infections.
