Fourteen pet tortoises - including four endangered spur-thighed tortoises - have been stolen from a house in Kent.
Thieves targeted the house in Sevenoaks overnight from Friday evening into the early hours of Saturday.
They left power tools and garden equipment but took all the tortoises from their enclosure.
A spokesman for the National Theft Register said four of the animals were microchipped and could not be sold without the correct paperwork.
The four microchipped animals were spur-thighed tortoises.
The others includes seven adult Horsfield tortoises, and three four-year-old Horsfield tortoises.
All the animals need special care and nutrition, the spokesman added.
Selling the tortoises would be a criminal offence, he said.
A reward has been offered to information leading to the arrest and conviction of the thieves.
