Two guinea pigs were stolen from a shed.
Burglars entered the family's unsecured garden shed, in South Street, between 10am on Tuesday, April 22, and 12.30am that night, before raiding the hutches.
The six-year-old male and four-year-old female pets, described as sandy coloured, are worth £40 each.
Essex Police believe a van and its drivers buying and selling scrap metal that day hold information.
Anyone with information should contact PC 72905 Alan Nock at Chelmsford police station.
