The rescue centre has capacity for just over 130 hedgehogs.
Willcox said if hoglets had been born there, the mothers were not disturbed until the little ones reached a couple of weeks old.
“We’ve got around 20 hand feeders at the moment, which is very tiring work,” she said.
On its website, the rescue writes, external that hedgehogs breed in spring and summer, mostly during May and June, producing litter of about four or five babies.
It adds the hoglets will start leaving the nest to forage with their mother at about four weeks old and will be independent by about eight weeks old.
But Willcox said the heat was “a huge factor” for the mass abandonments.
“This is for all wildlife, but hedgehogs in particular – if mums can’t find water or food source, they do very much have a survival of the fittest mentality, so we are seeing quite a large number of juveniles and babies coming in to us at the moment.”
