BUGS Bunny and Scooby Doo have been out and about to help raise the profile of alternatives to animal testing.
The cartoon characters joined activists from animal welfare group Passive Pressure in Bromley High Street.
Organiser Jan Yarker, 61, said: "Deliberately causing animals harm is wrong, so I have always been ethically opposed to animal testing.
"We have never had such a positive response as we did this time. Everybody was generous on a freezing cold day."
The event was organised to coincide with the World Week for Laboratory Animals.
It was held to support the Dr Hadwen Trust, a charity which researches illnesses such as asthma, cancer and multiple sclerosis without testing on animals.
