Is this really a suit of armor for Henry VIII’s cat named Dagobert?

That is an artwork made by Canadian artist Jeff de Boer. It has nothing to do with Henrik VIII who probably never had a cat called Dagobert.
This photo was taken at Ripley’s “Believe it or not” museum (probably in USA). You can see more Jeff de Boer’s artwork on Facebook. Here is another collection via Bored Panda, featuring mice and rat armor.
