Police Col. Ek Ekasart said police found 14 albino lions from Africa, hundreds of birds, meerkats, tortoises, peafowls, capuchin monkeys and other species from overseas and Thailand.
They said Montri Boonprom-on, 41, faces charges of possessing wildlife and carcasses and could face up to four years in jail and a fine of 40,000 baht ($1,300).
Ek said Montri owns an exotic pet shop at Bangkok's renowned Chatuchak weekend market and was previously convicted of wildlife trade.
Thailand is a hub of the international black market in protected animals. While the country is a member of a convention regulating international trade in endangered species, Thai law does not extend protection to many alien species.
Police also found a hornbill and a leopard, both protected by Thai law, which were packed in a box and were scheduled to be delivered to clients on Monday.
"We have been monitoring the location for a few days after the neighbors complained about the noise from the animals," Ek told reporters during the raid in a residential area of Bangkok's Klong Sam Wa district. "And if you looked through the gate, you could spot lions in the cage."
Montri told reporters the lions were shipped legally to Bangkok from Africa and were waiting to be moved to a zoo in Thailand's northeast. He did not explain why only 14 lions remained at his warehouse, while the documents showed he had imported 16.
The animals were confiscated and will be under the care of the Department of Natural Parks, Wildlife and Plant Conservation.
