The five-week-old kittens were tossed from their nest in Northumberland when the aftermath of Hurricane Katia struck Britain.
Winds reached up to around 70mph in the north of England last week as the remnants of the weather system moved over the UK.
In what were believed to be the worst storms for 15 years, trees were downed, waves engulfed roads and masonry collapsed.
The squirrels were found by a passer-by and taken to a vets' surgery, who passed them on to the Sanctuary Wildlife Care centre in Morpeth.
Their mother has still not been found so workers are feeding the tiny animals goats' milk by hand every three hours.
The Sanctuary is a family-run, not-for-profit organisation which cares for unwanted and injured animals across the north of England.
More cute pics -There are only around 140,000 red squirrels left in the UK, compared to over 2.5 million greys.
Red squirrels often build their nests - called dreys - in the forks of tree trunks.
They are weaned off their mother's milk after eight to 12 weeks when they have developed a complete set of teeth.
