how do indoor cats get fleas

Indoor cats can get fleas in several ways despite staying inside. Fleas can hitch a ride on humans, clothing, or shoes and jump onto indoor cats. Other pets in the household, such as dogs that go outside, can bring fleas inside too. Fleas can also be picked up at places where cats gather, like vet offices, boarding facilities, or shelters. Rodents like mice or rats that enter the home can carry fleas which then infect the cat. Additionally, moving into a new home can expose cats to flea eggs or larvae present in carpets and furniture, leading to infestations. Fleas can reproduce quickly once introduced, so even one flea can result in an infestation on an indoor cat.
