Flea infestations cause significant suffering to cats and trigger allergic reactions in sensitive individuals. Effective prevention is a foundational welfare intervention for all cats.
Flea infestations represent an entirely preventable source of suffering for cats that affects millions of animals whose owners either cannot access or haven't prioritized preventive care. A cat with flea allergy dermatitis experiences intense, constant itching from even a single flea bite - the allergic response is disproportionate to the infestation level. Kittens with heavy flea burdens can become seriously anemic. Even cats without allergy suffer the discomfort of multiple daily flea bites and the disruption to rest and grooming that accompanies an infestation. Modern flea prevention is highly effective, relatively inexpensive, and protects the cat, other pets, and the home environment. Ensuring access to preventive care in low-income households would eliminate significant preventable feline suffering.
