Thousands of cats are left in pet shelters every year. There are many genuine cases within these numbers – cats often outlive their elderly owners, and some people end up in situations where they can no longer care for the animal. Sadly, most cats are in there purely because their 'owner' couldn't bond well and changed their mind about keeping a pet. This is inexcusable and inhuman. Be sure of yourself before taking an animal home. Abandoning animals is a form of animal cruelty.
