Two students have been fined and banned for keeping animals for 10 years after putting a hamster in an envelope and posting it to an address.
David Jordan and James Cole, both 19 and students at Cambridge University, admitted to abandoning a hamster in a way that is likely to cause suffering.
In court on Tuesday, Jordan was fined £750 and Cole fined £500.
The hamster was found by a postman who spotted it chewing its way out of an envelope and rushed it to a vet.
Luckily the animal was found to be unharmed, but magistrates were told it had had a lucky escape.
In a statement read to the court vet Jillian Pearson told how the animal had no access to food or water and could have been crushed.
She said if the postman had not seen it peeping out of the envelope it would probably have been seriously injured or even killed during the sorting process.
RSPCA inspector Chris Nice described Jordan and Cole's actions as stupidity.
The hamster was later adopted by a nurse at the vet's practice it was taken to. It has been named First Class in honour of its amazing escape.
