Court documents revealed that the animals - kittens and rabbits - were often killed during the recordings.
The charges listed against Zhu are extremely detailed and graphic.
When she first appeared in court in April she pleaded not guilty to all 20 charges.
She was scheduled to have a case review hearing on Tuesday but after she did not turn up to court a warrant was issued for her arrest.
After her first appearance she had been remanded on bail with a number of strict conditions including being forbidden from using the internet unless she was at work and needed it for work purposes.
She was also ordered not to own or possess any animals or pets.
And she must allow police access to her home to carry out checks to ensure she is complying with the conditions.
Police could not comment on the case as it was before the courts.
