A litter of one-week-old kittens were found dumped inside a binon the hottest day of the year so far.
They were discovered wrapped inside a bag and inside a box by a member of the public.
It happened in Derby on the June 29, when temperates topped 30C.
A spokesman for the RSPCA said the kittens were dumped deliberately and whoever did it "had no intention for them to be found."
On the hottest day of the year a member of the public heard a chorus of loud and distressed squeaks coming from a black bin. Cases such as this highlight the importance of neutering your cats.
The four kittens were found without their mother and as a result will need round-the-clock care.
They will be available to be re-homed once they are eight-weeks-old and healthy.
