An Overview of Cat Wormer Types

Cat wormer products control or eradicate parasites that can cause discomfort, disease and possibly death. Cats contract worms while in the uterus, or after birth by exposure to infected mother's milk, prey, vomit or excrement. Signs of parasitic infestation include diarrhea, vomiting and worms, or worm pieces, found in feces or vomit. If you suspect your cat is suffering from a worm infestation, take a fresh sample of feces or vomit to your vet, who will recommend or prescribe the appropriate wormer for your cat.Cat wormers come in tablet, liquid, powder, paste and topical varieties. Some wormers are available in generic formulations.
