Flea control products should be used with care.

Products intended to treat cats and dogs for fleas make tens of thousands of pets sick every year, according to the US Environmental Protection Agency (EPA).

A significant rise in adverse reactions to “spot-on” flea-control products has led the EPA to warn consumers they should take extra care using them on their pets.
