It emerged the cat - whose name is Kitty - was a stray which had been adopted after wandering into a home half a mile away from where she was found.
Kitty had given birth in the comfort of the new surroundings and at about 3pm on Tuesday, had popped outside for her daily break from tending to her five offspring.
Celia suggested Kitty probably came into season after giving birth and drew the undivided attention of neighbourhood Tom cats as she ventured outside.
With the kittens at five weeks old, and at Kitty s age, she would have come back into season very quickly, according to the trust s founder.
