RSPCA officers had to rescue 136 pet mice from a single house after their owner failed to cope with a breeding frenzy that spiralled out of control.
The animal charity was called to the property in Atherstone, Warwickshire, in April following concerns over the rapid reproduction of the Natal multimammate mice.
Investigators discovered that none of the pets were neutered or separated by sex.
The breed, also called the African soft-furred mouse, is known for having many more nipples than a standard mouse – between 16 and 24 – meaning they are prolific breeders and can have large litters.
RSPCA inspector Richard Durant, who attended the property, said: “This was a situation which had got out of control.
"Some people may not realise that animals will inbreed and steps need to be taken to prevent this.
“It can be difficult to properly care for this number of animals so we were happy to step in to provide advice to the owner and to help to find the mice new loving homes.”
The inspectors worked alongside the RSPCA’s network of volunteer drivers to find the mice spaces at centres across the country.
They are now waiting for new owners at RSPCA branches in Derby, Norwich, Martlesham, South Cotswolds, Birmingham, Taunton and the Isle of Wight.
An RSPCA spokesperson added: "All the mice will need a spacious glass home with good ventilation where they are able to explore, but not escape.
"They will need cleaning out regularly and be provided with fun things to play with and chew.
"They are fascinating to watch, especially when they’re getting up to mischief.
"Multimammate mice aren’t always the easiest to handle, so the mice are ideally looking for an experienced home who understands their needs.
"If you’re interested in adopting a group of multimammate mice, please complete a Perfect Match form on the small furries page of the relevant centre’s website.
