The litter of three ginger boys and two girls were living in a dirty rabbit hutch without any bedding in a property in Stockwell, south London.
They were rescued by Inspector Phil Norman and taken to the RSPCA Putney Animal Hospital on June 30.
When they arrived, the four week old kittens were so filthy that they had to be bathed by the staff immediately to get rid of the dirt and smell.
They were also very underweight and small for their age.
The kittens were then moved to the RSPCA Middlesex North West branch on July 19 and named after famous rabbits, Roger, Peter, Bugs, Flopsy and Jessica, and will be looking for their forever home soon.
Sarah Blackband, animal welfare officer at the Middlesex North West branch, said: “They didn’t have the best start in life after being rescued from living in horrible conditions inside a rabbit hutch.
“They also had poor socialisation so have not been handled very much at all before they came to us.
“They are very timid and nervous but we are trying to get them used to human interaction and it seems to be working with some loving care from our staff they have now improved and are becoming playful and inquisitive.
“They still have a long way to go but are receiving lots of TLC in the meantime. Thank you to the inspector and the care given by the Putney nurses. We will now ensure they go to loving
The kittens are now ten-weeks-old and have had their first set of vaccinations. One of the kittens called Jessica has since found her forever home.
