The ISPCA and Born Free Foundation say they are disappointed that Meath County Council has given permission for a music festival at Tayto Park this summer.
The charities say the animals within the compound are likely to suffer considerable stress due to the loud music on the 29th and 30th of June.
The groups have written to the local authority saying it's irresponsible to allow this event to go ahead and say zoos have a duty to protect the animals in their care.
