On an autumn morning in Melbourne's west Lynn and her daughter-in-law Tahlia were driving along a suburban street, when they witnessed something most people would find incomprehensible.

"It was just horror, I couldn't believe someone would do that to an innocent animal. It was just shocking," Tahlia Kirkham said.

The pair immediately pulled over and started searching for the injured animals.

Unfortunately one of the kittens couldn't be found but the second, a Russian blue barely six weeks old, was discovered injured and hiding underneath a parked car.

The feline was in a bad way after suffering a fractured pelvis in the fall so the good Samaritans rushed the kitten to the local animal hospital for emergency surgery.

"I think we were all just so shocked that something like this could happen to an innocent animal like her," said Dr Elsa Vartola, a veterinarian at Lort Smith Animal Hospital in North Melbourne.

"[We] really wanted to make sure she was okay and get to the bottom of what was going on with her."

The kitten has battled through several surgeries during her 70-day stay in hospital.

"She actually had her tail amputated, there was a bad injury to her tail from the fall from the car," Dr Vartola said.

Tahlia and Lynn named the little kitten Dorothy and built a connection with her during the long recovery.

"Seeing how far she's come since then it makes that first moment feel so much better," Tahlia said.

In between hospital stays Dorothy has been fostered by animal hospital staff where she continued to build strength and recover from what vets called a horrific start to her life.

But after 10 weeks in hospital, Dorothy has found her happy ending.

The now three-and-a-half month old kitten has been adopted by the same family who rescued her.

"We're all just so happy for her, so happy for her and her new family. They're going to have a great future together," Dr Vartola said.
