The two females and three males were handed over after their mum’s owner was unable to afford to look after them as she already had other cats.
Named after the singers in ABBA and their manager, the 15-week-old feline siblings Agnetha, Anni, Bjorn, Benny and Stig are now looking for fur-ever homes.
Two eight-week-old female kittens, Mouse and Boo, are also hunting for new owners after being brought into the rescue centre.
Steph McCawley, supporter engagement officer at Chesterfield and North Derbyshire RSPCA, said: “We do find kittens come in through April to mid autumn; however this year we have experienced more kittens that we have in the last couple of years.
"The RSPCA strongly recommend that you get your cat neutered to help prevent unwanted pregnancies which can result in rescues like ours being overwhelmed with cats or kittens looking for new homes.
"Your female cat can be neutered from as early as four months old and is a simple procedure for your cat to have. It is the same for male cats also, as they will be attracted to a female cat from as young as this. Male cats who are not neutered will run a high risk of contracting FIV (the feline equivalent of HIV) which is another issue we experience with strays.”
