I don't know what his verdict will be.
Anna Esposito, wrote to Suffolk Superior Crown Court in Boston, US, to explain that a mistake had been made, but a jury commissioner replied saying the cat, named Tabby Sal, "must attend" on March 23.
Mrs Esposito had included a letter from her vet confirming that the cat was "a domestic short-haired neutered feline".
Tabby Sal had been entered by Mrs Esposito under the 'pets' section of the last census. "When they ask him guilty or not guilty? What's he supposed to say - miaow?" She said.
"Sal is a member of the family so I listed him on the last Census form under pets but there has clearly been a mix-up."
