- Cats were also raised in complete darkness during 'lazy eye' experiment
- Most of the subjects were given a fatal overdose after the procedures
- Ten prestigious universities said to be involved in the controversial testing
- Findings have been published in report which will be sent to the Home Office
The cruel procedures on the helpless subjects have been performed so scientists can improve their understanding of the human body.
Some of the animals were raised in complete darkness while others had one of their eyes stitched closed so scientists could analyse problems surrounding 'lazy eye'.
Others had their lungs deliberately collapsed during the brutal procedures and many were injected with paralysing drugs to stop them moving or breathing.
Scientists put the kittens under anaesthetic but when the experiments were finished, most of them were killed.
In a document seen by Mail Online, 10 universities including Cambridge were listed as having performed the controversial tests.
University College London gave the animals anaesthetic before screwing plates into their skull while they were placed face down.
Electrodes were then attached to their spine to 'investigate how abdominal nerve cells and muscles work together to allow for normal respiration, coughing and breathing.'
To test 'feedback mechanisms' between the eyes and the brain, they placed electrodes onto certain areas of the brain after removing parts of their skull.
The University of Bristol and Manchester Metropolitan University purposely bred cats for their experiments, which involved 'cutting through the skin and bone to gain access to the skull.'
At the Waltham Centre for Pet Nutrition, cats were placed on a strict diet to test how it affected 'blood fat constituents.'
Some of the food regimes, which lasted for six weeks, were high in fat and harmful.
Cardiff University and University of Edinburgh raised kittens and their mothers in 'complete darkness' to test how certain brain functions related to amblyopia, commonly known as ‘lazy eye’.
Some kittens were raised normally and then placed in complete darkness for a week. Other kittens had one eye closed through the use of sutures in the eyelids for up to seven days.
Major head surgery was done to prepare the kittens for testing. They were then anaesthetised and paralysed with a drug which prevented them from breathing or moving.
A hole was made through their throats into their tracheas (wind pipe) so that a tube could be inserted and used to artificially 'breathe' for them.
The Royal Veterinary College and the University of Glasgow were also said to be 'directly involved' in the experiments
