Bertha the bunny was left unable to move around her home after her hips collapsed in May. But ignoring vets' advice to put her down, her devoted owner created a specially-designed wheelchair to give her a new lease of life. Melanie James, who adopted Bertha as a baby four years ago, said: "When the vet said the nicest thing to do would be to put her down, she still had so much life. "I've actually seen dogs in wheelchairs and I thought 'if it works for a dog, then why not a rabbit?'
