The RSPCA was called to the Belvedere property, in Upper Sheridan Road, on April 21, after one of the cubs collapsed in the cold.
RSPCA inspector Rosie Russon attended the scene and freed the other cub, who was wedged in a cavity between an outside brick wall.
Both cubs, who are around five weeks old, were taken to the Kent-based Fox Project, a wildlife hospital that specialises in caring for foxes and fox cubs.
Rosie said: “One of the cubs had collapsed on the patio and I didn’t hold out much hope, but once I got them both into my van the unwell cub warmed up.
“The best course of action to take if people find fox cubs that appear orphaned is to wait to see if the parents/mother returns to collect them.
“The household had put out some food for them, but did the right thing by contacting the RSPCA because of the health of one of the cubs.”
She also explained that the cubs had been caught in torrential rain over Easter and were unable to find their way back home.
Despite a brief search for their den, Rosie prioritised getting the unwell cub specialist care.
She added: “If people come across similar situations with injured fox cubs then it is best they do not handle or transport fox cubs as they can become aggressive when stressed or injured.”
The RSPCA has advised the public to call them on 0300 1234 999 if they find a fox cub that is injured, sick, in immediate danger, or has its eyes closed.
They also directed people to their website for more information about fox cubs.
The two cubs are not albino foxes, which are very rarely sighted in the UK, but are light coloured due to a genetic mutation that affects pigment production.
While considered unusual, they are not as rare as albino foxes.
The Fox Project will release the cubs back into the wild near where they were rescued once they have fully recovered.
