I read the other day from the US that starving animals were being found regularly in homes deserted by mortgage defaulters.
The recent property crash there has created 'jingle mail', where the mortgagees put their house keys in an envelope and post off to the Banks, etc, then just walk away from their homes.
But some are leaving their animals locked inside, so when the house is finally opened perhaps weeks later, their dogs or cats have starved to death. Carpets, door frames are chewed and scratched in desperation before the slow slide to death.
I wonder whether there is a pay back factor in such cruel behaviour, where the bank has the horrible job of cleaning up.
