Those little pests can multiply faster than ...well, too darn fast! Don't forget to keep an eye out for fleas in areas that Simba likes to rest. Once he is protected, they may come after YOU!!! You may have to use a "flea bomb" on the room or house. Often there is more than one step needed to getting rid of those critters!

Good luck - you're being very smart to check on product interaction to protect your sweetie Simba!
