Thailand's tiger tourism business is booming and the captive tiger population is growing fast, experts say, more than two months after Thai wildlife authorities found scores of dead cubs while rescuing animals from the popular Tiger Temple.

Animal rights activists called on tourists to shun Thai animal attractions, which they say are cruel and should be shut down, after the Tiger Temple in Kanchanaburi province, west of Bangkok, closed in June.

Thai wildlife authorities vowed to inspect other tiger attractions, and confiscated 24 tigers from two venues, but the scrutiny has been short-lived.
