Apparently Britain is positively overflowing with owls that have been turfed out of their homes. Potter fans that fell in love with the wizard's mail-delivering pet owl, Hedwig, all went out and bought one. Now that Potter's all done and dusted the poor owls are getting dumped too.
Owl sanctuaries are apparently full to bursting, and there are fears that legions of the things have been illegally let loose into the British wilderness to either starve or take over from our natural, smaller owls. The problem is owls live for around 20 years and need pretty large places to flap about -- something most Potter fans just don't have.
This isn't the first time a film series has caused a load of homeless pets in Blighty though -- the Teenage Mutant Ninja Turtles film from the 1990s caused a mass uptake of terrapins. Once the kids got bored with their potentially rather dull pet, the poor things got dumped into our rivers and lakes.
