After the footage was released, PETA released a statement online, claiming that they had sent a letter to Warner Brothers requesting them to "commit to a ban on using live animals on tours."
In the statement, Mimi Bekhechi, Director at PETA, said that they wanted the studios to ensure that "Harry Potter tour stays magical – and not cruel – by keeping live animals out of it."
"Confining frightened owls to tiny cages where they can only chew at their tethers in frustration goes against every message of respect and kindness that JK Rowling's wonderful books taught us", Ms. Bekhechi added.

In light of the footage, a statement was made by Warner Bros. Studio Tour London, which said in an email to CNBC that the owls from the Harry potter film series "occasionally come to the Studio Tour" and "appear for short periods and are exclusively handled" by experts from Birds and Animals, the company that trains the animals.
The Warner Bros. statement added that they have Birds and Animals "to review this matter. It is essential to us all that the welfare of the birds and animals in their care is of the highest standard."
Birds and Animals responded to the footage too. In a statement, the company said "now that we have had the opportunity to see the footage, we have instigated a review of the issues raised. We will take appropriate action to ensure that the birds and animals always receive the very best care."
