You are likely seeing NEW fleas on your pet, which are jumping on your cat as it moves through infested areas. These fleas will be killed quickly by NexGard COMBO topical solution before they can reproduce. Depending on the severity of an already existing infestation as well as environmental conditions, you may continue to see new fleas jumping on your pet for 3 months or more. To prevent new infestations, continue to consistently give NexGard COMBO topical solution monthly and year-round.

Yes. Even indoor-only cats can become exposed to external and internal parasites. Fleas and ticks can be brought into the home by other pets or they can even hitchhike in on people. An infested pet will spread flea eggs throughout the house. These developing stages will survive in the areas that the infested pet frequents (carpet, cracks in hardwood floors, pet bedding, etc). Other animals, such as rodents and cockroaches, can be infected with intestinal parasites that can infect an indoor cat. And mosquitoes that can transmit heartworms can easily get indoors and pass heartworms to even indoor-only cats.

Cats get roundworms and hookworms  from common things in their environment including eating an infected rodent they’ve hunted. Infective hookworm stages can also penetrate the skin of a cat that visits a contaminated environment. Cats can get the tapeworm parasite by ingesting fleas. NexGard COMBO topical solution is the only broad-spectrum feline parasiticide that kills fleas and ticks, prevents heartworm disease, treats and controls roundworms, hookworms, and tapeworms.

The most common way to confirm an intestinal parasite infection is with a fecal test from your vet to detect the presence of parasite eggs. Prompt treatment of cats can help reduce further damage as well as mitigate the possibility of the worms spreading. Common signs include diarrhea, vomiting, weight loss, poor coat appearance, swollen belly, lethargy, dehydration, anemia, or blood in stool. Check their litter box often as another general sign of intestinal parasites are rice-like proglottids that show up in their feces.

Cats get heartworms by being bitten by an infected mosquito. One bite is all it takes.¹

Although most cats won’t show signs, once infected, cats may develop respiratory signs (including coughing or wheezing) that can be confused with other illnesses, such as allergies, asthma, or bronchitis. Other signs include difficulty breathing, vomiting, loss of appetite, and weight loss. Unfortunately, the first signs in some cats can be severe, and include collapse, seizures, and sudden death. Infection causes lasting damage in cats, and can result in lung disease, heart failure, and even death.

Yes, heartworm disease prevention is an essential part of a cat’s preventive healthcare regimen. While infection rates of heartworm disease are lower in cats than in dogs, cats are at risk of this devastating disease. The American Heartworm Society and Companion Animal Parasite Council recommend that all cats in the US receive heartworm disease preventive year-round.

Some internal parasites that can infect cats include heartworms, roundworms, hookworms, and tapeworms.

External parasites in cats can include fleas and ticks.

Fleas can cause itchy, painful skin conditions on your cat. Signs of fleas include scratching or biting at the skin, hair loss, scabs, and irritation.

If fleas go untreated, they can quickly multiply to cause an infestation. A single adult flea can lay up to 50 eggs per day, which means that a small number of fleas can grow into the thousands.² Fleas feed on a host’s blood, so they can also cause anemia, which can be severe in kittens or smaller animals. Fleas can also transmit other pathogens or parasites, such as tapeworms. An infested cat will scatter flea eggs throughout their home environment, and fleas can bite other animals, including humans.

Ticks can be hard to spot on cats. Since they bite the skin—underneath your cat’s fur—it can be difficult to locate them. They also may bite hard-to-reach areas, such as under the collar at the neck or beneath the armpits. Your cat may scratch at or gnaw on tick bite locations.

Yes. Ticks are carriers for several dangerous diseases. If a tick that is carrying a pathogen bites a cat, that cat is at risk of becoming infected as well. Ticks can also transmit various life-threatening tick-borne illnesses.
