Mrs Mclean, 29, told the Press and Journal: "I just told my sister-in-law to stop the car because I had spotted Tara.
"I called her name and she came running towards me and was rubbing herself against my leg.
"It was weird - she seemed to remember her name and wasn't scared or anything.
"To see her after so long was definitely a shock to the system. I still can't believe it."
Mrs Mclean has since posted a message on a local Cats Protection website in the hope of finding out who has been taking care of Tara for the last six years.
