Ross Allan, a vet based in Glasgow, discovered she was intersex, with elements of both male and female external genitalia.

This was causing her "significant" discomfort and abrasions, so she underwent a "complex" operation to improve her quality of life.

Mr Allan said Molly, now around 18 months old, has made a complete recovery after the surgery last June.

Mr Finlay told BBC Scotland's Kaye Adams Programme: "We got Molly in November 2015 and noticed that around the house she would squat to do her pees but outside she would lift her leg.

"I mentioned this early on in 2016 to one of Ross's colleagues and they came up with the probability that she was a hermaphrodite, both sexes.

"They did MRI scans and X-rays, and eventually she was operated on in 2016. We still call her Molly."
