Book 1: Puppy Prozac

In Wurtzel's final part of her memoir, Epilogue: Prozac Nation, she begins to describe a situation with her friend's cat; the cat was brought to a vet because the friend had noticed some strange behavior. The cat was chewing her fur off and the vet attributed this "excessive grooming disorder" to being lonely in it's apartment. This condition is treatable in humans with Prozac, and the vet gives the cat Prozac in a "feline-size prescription" (Wurtzel 295). Not only is Prozac approved for people, it is used to treat some animal disorders. Has this gone too far, or are we helping pets by giving them antidepressants?
