The agency will have offices in Barcelona, Birmingham, London and Paris, offering booking and marketing services as well as support for touring shows and exhibitions.
AMP founder Mike Molloy has become Big Cat Europe managing director as part of the deal.
"We are looking forward to announcing new clients and projects in the coming months," said Molloy. "I will be working with Nick Morgan, CEO of Big Cat Group, to integrate the teams of the two companies to make these new projects a reality."
The two founding firms have worked together in the past, including for the debuts of exhibitions 'Bodies Revealed' in October 2009 and 'CSI: The Experience' in March this year.
