Where is animal testing illegal?

No, testing on animals is legal in the US and heavily regulated. All animals used for testing and research must be under the care of a licensed accredited veterinarian, usually one who specializes in laboratory animal medicine. All protocols must be written in exact detail and reviewed by an IACUC (Internal Animal Care and Use Committee), who must agree that this protocol is proper, humane and would result in valuable information being gained. For instance, an IACUC would not approve a protocol that involved breaking an animal's bone to determine if the break hurt - this information is well established (yes, it hurts like crazy) and is inhumane.
