THREE adorable kittens at a Worcestershire rescue shelter have been melting hearts online.

Maribel, Marjorie and Millicent are three weeks old and are currently in the care of the RSPCA Worcester and Mid Worcestershire branch.

The kittens have been with staff for three days after a member of the public reported they had been left on a doorstep.

On Facebook, the kittens have received hundreds of likes and lots of shares and comments from people across the county.

Staff at the RSPCA Worcester and Mid Worcestershire Branch in Kempsey are hand-rearing the kittens which require three hourly feeds, day and night.

Despite the interest from the public, it will be several weeks before they are ready to be adopted. 

A spokesperson for the branch said: "At just three weeks old, they already have bags of purr-sonality and cattitude.

"They're running us ragged with their demands for feeding (three-hourly bottle feeds, though if they had their way they'd be more frequent).

"It'll be a while before they are ready to fly the nest, but we can already see that they are a very bonded trio, so we hope that they'll find a home where they can all stay together."
