Many solid white cats are pink-skinned—and, literally, thin-skinned. This has led to occasional health problems and even death from a flea bath. Some of the solutions used to kill fleas can kill the cat as well, even when veterinarians or their technicians give the bath.
The pink skin of a white cat is more sensitive to flea baths (and any kind of chemical) than the skin of other cats. If you own a white cat, be aware of this, and don’t be shy about reminding your vet that your pet has sensitive skin.
