Oral flea control products, or "flea pills," are given to a cat by mouth to kill fleas and prevent fleas.

The spray may also be more cost-effective, compared to the ampules. This does make it a favorite of shelters and rescues taking in stray cats with active infestations that they don’t want to risk spreading to other animals in their care.
