LOOK: Birmingham kittens born with extra toes
These kittens' claws certainly gave their Birmingham owners 'paws for thought.'
Connie and Clyde were rescued by the Cats Protection Birmingham Adoption Centre, after they were abandoned at just eight weeks old.
Rescuers were startled to discover the brother and sister's strange condition - the polydactyl pair both have extra toes.
The 'thumb-like' addition is a genetic quirk that gives them greater climbing abilities.
They now have pride of place in with Sue Dudley in her Northfield home, she is full of praise for their talents.
Cats like this are more commonly found in the US and Canada where they were used as ship’s cats.
They are not so popular in Europe where they were historically destroyed over superstitions of witchcraft.
