Symptoms of parasites in cats include diarrhea, bloody stool, vomiting, coughing or trouble breathing, according to WebMD. Cats or kittens may also experience weight loss, constipation, bloating around the abdomen or worms visible in the stool.
Some cats do not have any symptoms, explains the VCA Animal Hospitals. In rare cases, an intestinal parasite infection can cause sudden death.
Cats who eat rodents, hunt or live outdoors are more prone to worms and parasite infections, explains WebMD. Cats may also be at risk if they do not receive regular preventative health care or they frequent areas where other animals defecate. A veterinarian prescribes or administers deworming medications to treat a cat for worms due to an intestinal parasite infection.
Cat owners can help prevent parasite infections by having a veterinarian regularly test and vaccinate their animals, explains VCA Animal Hospitals. A fecal examination is a common type of test to detect worms or parasites. Veterinarians also recommend regular checkups and monthly preventative medications to prevent heartworm and parasites. Cat owners should practice preventative measures that include keeping cats indoors; making sure the yard, pets and home are free from fleas; and frequently disposal of stool from the litter box, notes WebMD.
